Quick ITSM Basics
What is ITSM?
IT Service Management (ITSM) is the discipline of planning, delivering, operating, and improving IT services to meet business needs. It uses structured processes-like Incident, Request, Problem, and Change-to restore service quickly, manage risk, and prevent recurrence. ITSM also relies on measurable targets (SLAs/OLAs) and continual improvement using KPIs such as MTTR and FCR.
Incident vs Request
An Incident is an unplanned interruption or degradation of a service (e.g., email outage, VPN down). A Request is a user asking for a standard, pre-defined service (e.g., software install, access request). Incidents prioritize rapid restoration and communications; requests prioritize fulfillment through approvals, tasks, and catalog workflows with predictable service expectations.
SLA vs OLA
An SLA is an external service commitment (response or resolution time) agreed with customers or the business. An OLA is an internal target between support teams that helps meet the SLA. SLAs measure service performance; OLAs measure internal delivery. A UC (Underpinning Contract) is a vendor commitment that supports internal OLAs and customer SLAs.

Core ITSM processes
- Incident (including Major Incident + communications)
- Request Fulfillment (Service Catalog, Record Producers, approvals, tasks)
- Problem (RCA, workaround, Known Error, prevention)
- Change (Standard/Normal/Emergency, risk, CAB/ECAB)
- Knowledge (KCS) (create, reuse, improve; deflection)
- CMDB/Services (CIs, relationships, dependency; service offerings)
- Service Level Management (SLA/OLA/UC, breach, timers, pause conditions)
- Reporting/PA (KPIs like MTTR, FCR, backlog aging, change failure rate)
Incident vs Request vs Problem vs Change
| Process | What it is | Use when |
|---|---|---|
| Incident | Service interruption/degradation | “Payroll app down”, “VPN unstable”, “Email not sending” |
| Request | Standard service fulfillment | “New laptop”, “VPN access”, “Software install” |
| Problem | Root cause behind incidents | Repeat outages, major incident follow-up, trending CI failures |
| Change | Controlled production modification | Patching, firewall rules, releases, config updates |
Priority matrix (Impact × Urgency)
| Urgency: High | Urgency: Medium | Urgency: Low | |
|---|---|---|---|
| Impact: High | P1 | P1/P2 | P2 |
| Impact: Medium | P2 | P3 | P3 |
| Impact: Low | P3 | P4 | P4 |
Common pitfalls
- Overusing On Hold to pause SLA timers without valid “pause conditions” governance
- Poor routing due to bloated categories and unclear assignment groups
- Missing CI/service data → weak impact analysis and misleading reports
- Noisy notifications and unclear comms during Major Incidents
- Over-customization (heavy Business Rules/scripts) causing performance issues
Best practices (say these in interviews)
- Prefer service offerings for user selection, map to supporting CIs for dependency/impact
- Use KCS: link knowledge to tickets, track reuse/deflection
- Keep automation maintainable: Flow Designer for new work, optimize server-side logic
- Protect data: least privilege ACLs, role design, safe comments (no secrets/PII)
- Measure outcomes: MTTR by stage, FCR, backlog aging, reopen rate, change failure rate
ServiceNow ITSM Interview Questions for Freshers (0–2 yrs)
If you’re targeting junior roles and searching servicenow itsm interview questions for freshers, focus on lifecycle, SLAs, routing, and clean documentation.
What fields matter most when you log an incident?
Answer: Caller, short description, detailed description (symptoms + errors), service/CI (if known), impact, urgency, and contact method. Good data helps routing and SLA accuracy.
Tip: Include “what changed” and “when it started” to speed troubleshooting.
Explain incident states and what you do in each.
Answer: New (triage), In Progress (work + updates), On Hold (waiting with reason), Resolved (fix/workaround applied), Closed (final confirmation/auto-close).
Tip: If “On Hold,” always document the reason and next action owner.
What’s the difference between “Resolved” and “Closed”?
Answer: Resolved indicates the support team believes it’s fixed; Closed finalizes the record after confirmation or a defined window. Policies vary by company.
Tip: Mention “closure codes and resolution notes must be audit-ready.”
How do you decide Impact vs Urgency on a call?
Answer: Impact = scope (users/services/revenue). Urgency = time sensitivity (workaround, deadlines). Priority comes from the matrix.
Tip: Payroll down at month-end = high impact + high urgency = P1.
What’s a Major Incident (at a junior level)?
Answer: A critical incident with widespread impact that needs rapid coordination, structured comms, and often a dedicated incident manager.
Tip: Say “bridge call + comms cadence + child incidents linked.”
Work notes vs Additional comments?
Answer: Work notes are internal for agents/teams; additional comments are visible to the requester.
Tip: Never paste sensitive technical details or credentials into user-facing comments.
What is an SLA timer and what can pause it?
Answer: SLA timer tracks response/resolution targets. It can pause based on conditions like state = On Hold with specific reasons (Awaiting User/Vendor) or schedules.
Tip: Pauses must be governed to avoid “gaming” SLAs.
What is a breach and what should you do before it happens?
Answer: A breach occurs when SLA target time exceeds. Before breach, escalate, re-route if misassigned, and ensure correct priority/hold reason.
Tip: Proactive escalation at “warning thresholds” prevents breaches.
What is an assignment group?
Answer: The resolver team responsible for the ticket (Service Desk, Network, Messaging, IAM).
Tip: Reassignment count is a quality indicator-lower is better.
What’s the difference between Incident and Request?
Answer: Incident restores service; Request fulfills a standard service through catalog workflows and approvals.
Tip: Admin access should be a request, not an incident.
What’s a Service Catalog and why do organizations push it?
Answer: It’s a structured set of requestable services with approvals and fulfillment tasks. It standardizes delivery and reduces email chaos.
Tip: Example: “VPN access request → manager approval → IAM fulfillment.”
Explain REQ, RITM, and Catalog Task.
Answer: REQ = the order, RITM = each requested item, SCTASK = fulfillment tasks assigned to teams.
Tip: Quote the chain: “REQ → RITM → SCTASK.”
What is a Record Producer?
Answer: A catalog form that creates a record (often incident/case) using user-friendly questions.
Tip: Great for “Report an Issue” portal experiences.
What is Knowledge Management (KCS) in simple terms?
Answer: Capture and improve reusable solutions while working tickets; publish validated articles to reduce repeat work.
Tip: Link the article to the incident for traceability.
What’s a CI?
Answer: A Configuration Item stored in the CMDB (app, server, service). Linking helps routing and impact analysis.
Tip: If CI is unclear, choose the service offering when available.
Why do CI relationships matter?
Answer: They show dependencies (app depends on DB). During outages, relationships help assess upstream/downstream impact.
Tip: Mention “dependency” explicitly-interviewers like that.
What is a Change Request?
Answer: A controlled request to modify production with risk review, approvals, and implementation/rollback plans.
Tip: Fixing a recurring issue in production often requires a change.
CAB vs ECAB?
Answer: CAB reviews planned/high-risk changes; ECAB approves emergency changes quickly during major incidents.
Tip: Emergency still needs documentation after restoration.
What is a PIR?
Answer: Post-Incident Review capturing timeline, impact, learnings, and action items with owners/dates.
Tip: PIR actions must be tracked to closure-otherwise outages repeat.
What’s the difference between Problem and Change?
Answer: Problem finds root cause; Change implements controlled fixes.
Tip: “Problem identifies; Change modifies.”
What is a Business Rule (high level)?
Answer: Server-side logic triggered on insert/update/delete/query. Used to enforce process rules or data quality.
Tip: Keep server-side logic efficient to avoid slow transactions.
What is a Client Script (high level)?
Answer: Browser-side script controlling form behavior/validation (onLoad/onChange/onSubmit).
Tip: Use UI Policies for simple required/visible/read-only logic.
What is a UI Policy?
Answer: No-code rules to make fields mandatory/read-only/visible based on conditions.
Tip: UI Policy is easier to maintain than custom scripts for basic behavior.
What is an ACL?
Answer: Access Control List rules controlling read/write/create/delete on tables/fields/records based on roles/conditions.
Tip: Least privilege is the standard security principle.
Roles vs Groups-how are they different?
Answer: Roles grant permissions; groups organize teams and often drive assignment. Users can belong to multiple groups and have multiple roles.
Tip: Avoid giving broad roles when group-based assignment solves the need.
What is impersonation used for?
Answer: Testing the user experience and verifying access without needing user credentials.
Tip: Good for debugging “why can’t this user see the KB article?”
What is inbound email processing used for?
Answer: Creating/updating incidents/requests from emails (support mailbox).
Tip: Proper threading prevents duplicates.
What’s a common “bad ticket” sign you should fix immediately?
Answer: Vague short description, missing impact/urgency logic, no next-step owner, or no user update after state changes.
Tip: Write updates as “what happened + what we’re doing + when next update.”
What KPIs should a junior analyst know?
Answer: MTTR, FCR, SLA compliance/breach rate, reopen rate, backlog aging.
Tip: Explain how your actions affect MTTR (routing and comms).
One thing you’d do to reduce reopens?
Answer: Confirm resolution steps, document clearly, ensure user understands next actions, and link knowledge when relevant.
Tip: “Resolution notes should be reusable.”
ServiceNow ITSM Interview Questions for Experienced (3–6 yrs)
If you’re interviewing mid-level roles and searching servicenow itsm interview questions for experienced, expect deeper governance, CMDB usage, automation decisions, and reporting.
35 questions. Each includes a detailed answer + “Interview Tip”.
How do you run a Major Incident end-to-end in ServiceNow?
Answer: Define trigger criteria (priority + service impact), assign incident command roles, open a bridge, and set a communication cadence. Relate child incidents, drive resolver engagement with tasks, and keep a single source of truth (status updates + timeline). After restoration, conduct PIR, create a problem record for RCA, and ensure corrective actions become tracked changes/requests.
Interview Tip: Emphasize communications discipline as part of restoration.
How do you design SLAs with pause conditions without encouraging misuse?
Answer: Keep pause states limited (e.g., On Hold + Awaiting User/Vendor), enforce evidence in work notes, restrict hold changes via roles, and report “time on hold” separately. Use warning thresholds for escalations and define OLAs per resolver team so SLAs are realistically achievable.
Interview Tip: Say “govern hold reasons” to show maturity.
How do you align SLA/OLA/UC so vendors don’t break your SLA?
Answer: Set OLAs that support SLA buffers, and map vendor UCs to internal OLAs (e.g., ISP restore within 60 minutes). Track vendor delay time explicitly and use reports for vendor performance reviews.
Interview Tip: Mention UC as “vendor underpinning contract”.
What’s your approach to improving routing and reducing ticket ping-pong?
Answer: Prefer service offerings over deep category trees, map service offering to assignment groups, and use CI ownership where CMDB is mature. Review reassignment trends monthly, simplify categories, and create a triage queue for ambiguous tickets.
Interview Tip: Quote metrics: reassignment count and time-to-assign.
How do you use CMDB relationships during incidents?
Answer: Use CI/service relationships for impact assessment and faster troubleshooting: identify upstream dependencies (DB, network) and downstream services impacted. Improve data quality by constraining CI selection, auto-populating from discovery/service mapping, and driving ownership.
Interview Tip: “Relationships enable dependency impact analysis.”
When do you open a Problem record and what do you capture first?
Answer: Open problems for recurring patterns, major incidents, high-cost outages, or when workarounds exist but root cause is unknown. Capture symptoms, frequency, affected CI/service, known workaround, and a hypothesis backlog.
Interview Tip: Mention Known Error/KEDB as the target output.
How do you ensure RCA quality isn’t just “human error”?
Answer: Require evidence: timeline, logs, monitoring, recent changes, contributing factors, and control gaps. Use structured methods (5 Whys), validate with owners, and convert findings into corrective actions and governance updates.
Interview Tip: “Evidence-based RCA” is a strong phrase.
How do you connect Problem → Change → Incident traceability?
Answer: Link repeated incidents to the problem, raise change requests for production fixes, and relate the change back to the problem. This enables reporting on “problem-driven changes” and whether incident volume decreases post-fix.
Interview Tip: Traceability is key for audit and learning.
Explain Standard vs Normal vs Emergency change in practical terms.
Answer: Standard is pre-approved, repeatable, low risk; Normal follows full lifecycle with risk assessment and approvals (often CAB); Emergency is urgent to restore service, uses ECAB, and requires strict after-action documentation.
Interview Tip: “Emergency ≠ no controls.”
What are change models and why do they matter?
Answer: Change models standardize lifecycle, approvals, and required evidence by change type/risk. They reduce inconsistency, speed low-risk work, and strengthen audit readiness.
Interview Tip: Say “models reduce variance.”
How do you prevent change collisions?
Answer: Use schedules, blackout windows, CI/service scope visibility, and CAB governance. Encourage teams to declare affected CIs and impacted services, and reschedule lower priority changes to reduce risk stacking.
Interview Tip: Mention blackout vs maintenance windows.
Flow Designer vs Workflow-how do you choose?
Answer: Prefer Flow Designer for new automations (approvals, task creation, notifications) because it’s easier to maintain and reuse actions. Keep Workflow mainly for legacy processes that already depend on it.
Interview Tip: “New build = Flow Designer” is a safe stance.
13) Business Rule vs Client Script vs UI Policy-how do you decide?
Answer: UI Policy for basic field behavior; Client Script for richer client-side validation; Business Rule for server-side enforcement, data integrity, and cross-record actions. Keep server-side logic minimal and performance-safe.
Interview Tip: Mention “server-side for integrity, client-side for UX.”
How do you avoid performance issues from scripting?
Answer: Reduce synchronous server-side work, avoid heavy loops and complex queries, use conditions, and push non-critical work async where safe. Monitor slow transactions and optimize frequently triggered logic.
Interview Tip: “Optimize what runs often.”
How do you design notifications that users actually read?
Answer: Trigger on meaningful transitions (assignment, hold, resolution), keep templates short and actionable, separate internal vs external comms, and avoid spamming users on every field update.
Interview Tip: “Signal > noise.”
How do you stop inbound email duplicates?
Answer: Use robust email threading, ignore auto-replies, validate sender domains, and ensure replies update existing records instead of creating new ones. Test across clients (Outlook desktop/mobile).
Interview Tip: Mention “auto-reply loop prevention.”
How do you handle “Awaiting User” holds ethically?
Answer: Only pause when user action is truly needed, send reminders, document what’s needed, and auto-close after policy-defined inactivity (with warnings). Report hold time separately.
Interview Tip: “Transparency prevents SLA gaming.”
Catalog governance: what do you put in place as volume grows?
Answer: Ownership per item, naming standards, retirement rules, regular reviews, and demand analytics. Ensure consistent approvals, SLAs, and fulfillment tasks.
Interview Tip: Call out “catalog sprawl.”
How do you design a secure admin-access request catalog item?
Answer: Collect beneficiary, role requested, justification, cost center, approvals (manager + application owner/security), and fulfillment tasks to IAM. Add validations to prevent privileged access without proper approvals and keep an audit trail.
Interview Tip: Use “least privilege and auditability.”
How do you measure and improve MTTR?
Answer: Break MTTR into stages (time to acknowledge, assign, restore). Improve routing, shift-left common fixes with KCS, automate repetitive tasks, and implement swarming for complex incidents.
Interview Tip: Mention “time-to-assign” as a key lever.
What KPIs do stakeholders typically want?
Answer: SLA compliance/breach risk, MTTR, ticket volume, backlog aging, reopen rate, FCR, top failing services/CIs, and change failure rate. Execs prefer trends; ops prefers queue health.
Interview Tip: Tailor dashboards by audience.
Reports vs Performance Analytics-how do you explain it?
Answer: Reports provide snapshots; Performance Analytics tracks trends over time with targets and breakdowns. Use PA for scorecards and continuous improvement programs.
Interview Tip: “PA is for trend + targets.”
How do you improve CMDB data quality where it actually matters?
Answer: Focus on top services by volume/impact, define CI ownership, automate discovery, validate key relationships, and constrain CI selection to relevant items.
Interview Tip: “CMDB is a product, not a one-time project.”
How do you handle VIP users without breaking governance?
Answer: Provide faster engagement and comms, but do not bypass approvals or change controls. Document decisions and keep audit trails.
Interview Tip: “VIP doesn’t mean skipping risk controls.”
How do you implement a Major Incident communications template?
Answer: Include impact, affected services, workaround, ETA/next update time, actions underway, and a link to the single source of truth. Keep it consistent and time-stamped.
Interview Tip: Mention a 15–30 minute cadence for P1s (policy-driven).
How do you decide what to automate?
Answer: Automate repeatable, low-risk tasks (routing, standard approvals, reminders, task creation). Keep manual steps for risk decisions and complex judgment. Always include error handling and audit logging.
Interview Tip: “Repeatable + low risk = automate.”
What’s your approach to Change risk assessment?
Answer: Evaluate CI/service criticality, blast radius, rollback complexity, testing completeness, and timing (blackouts/peak periods). Use data from prior change failures and incidents.
Interview Tip: Mention change failure rate as feedback.
How do you handle post-change verification and review?
Answer: Verify against test criteria, monitor for incident spikes, capture outcomes in review state, and link any failures to problem/PIR actions.
Interview Tip: “Verification is part of the change, not optional.”
How do you reduce “no update” complaints from users?
Answer: Define comms rules (updates on assignment/hold/resolution), ensure agents use additional comments appropriately, and standardize templates with next steps.
Interview Tip: “User-facing comms should always include next update time.”
What’s a practical approach to reducing reopens?
Answer: Improve resolution quality, verify restoration, document steps clearly, link knowledge, and ensure the user understands any post-fix action (reboot, reconnect, cache clear).
Interview Tip: Mention reopen rate as a quality KPI.
How do you troubleshoot “user can’t see knowledge article” issues?
Answer: Check knowledge base permissions, user criteria, article state (draft/published), role/ACL controls, and whether the article is in a restricted KB. Test via impersonation.
Interview Tip: “User criteria + KB permissions” is the usual root cause.
How do you secure ITSM data with roles and ACLs?
Answer: Use least privilege roles by job function, group membership for assignment, and ACLs for record/field protections. Add separation of duties for admins and approvers.
Interview Tip: Mention periodic access reviews.
How do you implement REST integration responsibly?
Answer: Use secure auth (OAuth per policy), define field mappings, validation, retries, rate limits, and monitoring. Log failures with correlation IDs for troubleshooting.
Interview Tip: “Error handling is part of integration design.”

How do you run a continual improvement cycle?
Answer: Use trends (top services/CIs, breach clusters), prioritize by impact/effort, deliver improvements (automation, knowledge, monitoring fixes), and measure before/after outcomes.
Interview Tip: “Measure → improve → re-measure.”
What’s a common mid-level implementation mistake?
Answer: Adding more customization instead of simplifying process and improving data inputs (service offering selection, better templates, better routing).
Interview Tip: “Governance + usability beats complexity.”
ServiceNow Interview Questions for 7 Years Experience (Senior/Lead)
This section targets servicenow interview questions for 7 years experience-architecture, scale, security, governance, and stakeholder leadership.
25 questions total, including 5 leadership STAR answers.
How do you define an ITSM operating model across regions?
Answer: Clarify L1/L2/L3 responsibilities, on-call/escalation paths, process owners, and service owners. Standardize major incident roles, comms cadence, OLAs, and service review governance. Build shared dashboards for queue health and SLA risk so regions operate consistently.
What’s your strategy for service taxonomy: services vs offerings vs CIs?
Answer: Use offerings for user selection and reporting; map offerings to supporting CIs and relationships for dependency impact. Avoid forcing agents to guess CIs-design to reduce friction while preserving data quality.
How do you keep ServiceNow performant at high scale?
Answer: Minimize synchronous server-side scripting, optimize queries, avoid heavy loops, use indexing carefully, and prefer async for non-critical work. Establish guardrails: code reviews, performance testing, and a pattern library for common automations.
Describe a mature ACL strategy for ITSM.
Answer: Role design aligned to job function, group-based assignment, least privilege, and separation of duties. Protect sensitive fields with field ACLs, log impersonation/admin activity, and run periodic access reviews. Keep ACL logic simple and testable.
How do you handle governance when teams want “fast but risky” changes?
Answer: Offer controlled speed: standard change models for repeatable low risk, emergency change with ECAB for urgent restoration, and strict evidence requirements for high-risk normal changes. Make risk acceptance explicit and documented.
How do you manage stakeholder expectations when SLAs are unrealistic?
Answer: Use data: backlog drivers, vendor dependencies, and stage-based MTTR. Provide options: adjust SLAs, tighten OLAs, automate, shift-left, or increase capacity. Drive a decision with clear tradeoffs and get written agreement.
What KPIs matter most at senior level?
Answer: MTTR (by stage), SLA compliance + breach risk, backlog aging, reopen rate, FCR, major incident volume + PIR completion, change success rate and change failure rate, and service health trends.
How do you build a continuous improvement program that actually ships changes?
Answer: Use a recurring forum with a prioritized improvement backlog, owners, timelines, and benefits tracking. Focus on high-impact drivers: routing quality, knowledge reuse, major incident learnings, change failure prevention, and CMDB improvements where they matter most.
How do you design major incident communications for executives?
Answer: Keep updates short: impact, affected services, workaround, ETA/next update time, and actions underway. Ensure a single source of truth and avoid conflicting messages from multiple teams.
How do you handle CMDB governance beyond “data cleanup”?
Answer: Define ownership, automate discovery, validate critical relationships, and measure CMDB health where it impacts operations (routing and impact analysis). Prioritize improvements by “top services by incident volume” instead of trying to perfect everything.
How do you manage change collision and blackout governance?
Answer: Enforce blackout periods for business-critical windows, require affected CI/service declarations, and use CAB discipline for risk stacking. Emergency exceptions must have ECAB approval and after-action review.
How do you reduce change failure rate over time?
Answer: Standardize evidence requirements (test/rollback plans), improve scheduling discipline, implement peer review gates, and run post-change analysis on failures to update controls and templates.
How do you decide between configuration vs customization?
Answer: Prefer configuration (forms, UI policies, flows, notifications) first. Customize only when it materially improves outcomes and remains maintainable. Enforce design standards and deprecate one-off scripts.
How do you manage “shadow processes” (email approvals, spreadsheets)?
Answer: Identify why they exist (speed, missing workflow, poor UX), design a better in-platform experience (catalog + automation + reporting), then enforce adoption with governance and training.
How do you ensure reporting isn’t “greenwashing”?
Answer: Include leading indicators (breach risk, backlog aging), quality indicators (reopen rate), and hold-time visibility. Document KPI definitions and audit pause/hold behaviors to ensure metrics reflect reality.
Tell me about a Major Incident you led (STAR).
Answer: Outline scope, your role, comms cadence, how you coordinated resolver groups, how you restored service, and how PIR actions were tracked to completion. Quantify outcomes (downtime reduced, MTTR improved).
Describe a time you pushed back on a risky change (STAR).
Answer: Explain your risk assessment, alternatives offered (window, rollback, testing), stakeholder alignment, and the final outcome. Show calm escalation and governance.
Tell me about improving SLA compliance without adding headcount (STAR).
Answer: Describe routing improvements, automation, knowledge reuse, OLA alignment, and how you measured reduction in breaches and MTTR.
Describe resolving conflict between resolver groups over ticket ownership (STAR).
Answer: Show how you used data (reassignment trends), clarified ownership boundaries, updated routing rules/OLAs, and reduced ping-pong behavior.
Tell me about a continuous improvement initiative you owned (STAR).
Answer: Use a before/after story: baseline metrics, change implemented, adoption plan, and measurable outcomes (incident reduction, deflection increase, change failure drop).
What’s your approach to mentoring and standards?
Answer: Establish reusable patterns, review checklists, pair sessions, and a “why” culture: ITIL intent + platform best practices. Promote safe testing and strong documentation.
How do you approach integration strategy (REST, email, identity) at scale?
Answer: Standardize auth, error handling, monitoring, and ownership. Use correlation IDs, data contracts, and rate-limit awareness. Keep integrations auditable and resilient.
How do you manage security best practices in communications?
Answer: Prevent PII/secrets in comments/emails, template-safe notifications, field ACL protections, and training. Audit impersonation and elevated access regularly.
How do you drive adoption of self-service and deflection?
Answer: Improve portal usability, invest in KCS quality, measure deflection and CSAT, and focus on top-volume requests first (password resets, access). Iterate using analytics.
What’s one “non-negotiable” governance practice you enforce?
Answer: PIR actions must have owners and due dates and be tracked to closure-otherwise you repeat outages. Second: change evidence (test/rollback) for anything affecting critical services.

FAQs
Is ITSM enough to get a ServiceNow job?
ITSM is a strong foundation, especially for junior roles, but hiring teams also want platform basics: record lifecycle, SLAs/timers, catalog flow (REQ/RITM/SCTASK), basic security (roles/ACLs), and automation awareness (Flow Designer).
How to prepare for a ServiceNow ITSM interview in 7 days?
Learn process flows first (Incident/Request/Problem/Change), then master SLAs/priority/routing, then catalog structures and automation. Finish with scenario practice and KPI storytelling (MTTR, FCR, change failure rate). Use the plan below.
SLA vs OLA difference?
SLA is the external service commitment; OLA is an internal support target. OLAs should support SLA achievement and make accountability across teams measurable.
Flow Designer vs Workflow?
Flow Designer is the modern low-code automation tool preferred for new work; Workflow is older/legacy and still maintained in some environments. In interviews, say you prefer Flow for new builds unless legacy constraints exist.
How CMDB helps Incident Management?
CMDB links tickets to CIs/services and their relationships, enabling better routing, impact analysis, and trend reporting. The value depends on data quality and meaningful relationships, not just having a CMDB populated.
What’s the best way to answer “How do you set priority”?
Use the matrix: Impact (scope) × Urgency (time sensitivity). Give a real example (payroll outage vs single user with workaround).
What’s the difference between Major Incident and Problem?
Major Incident is about rapid restoration and communications; Problem is about RCA and prevention after service is stable.
What technical topics matter for ITSM interviews?
Business Rules, Client Scripts, UI Policies, Notifications, Flow Designer, ACL security, CMDB basics, and integration basics (REST/email).
What metrics should you mention for ITSM?
MTTR, FCR, SLA compliance/breach rate, backlog aging, reopen rate, reassignment count, major incident PIR completion, change success/failure rates.
What are common “red flags” interviewers listen for?
SLA gaming, skipping approvals, blaming individuals in RCA, over-customization without governance, and poor user communication.
Conclusion + 7-day study plan
This guide is designed to outclass short, generic lists by combining process + platform + real operational judgment. If you can explain (1) how you restore service and communicate during P1s, (2) how you prevent repeats through Problem and controlled Change, and (3) how you enforce SLAs, security, and data quality with maintainable automation-you’ll sound like someone who has done real implementations.
- Day 1: Incident lifecycle + states + communication + priority matrix practice
- Day 2: SLAs/OLAs/UCs + timers + pause conditions + breach prevention
- Day 3: Service Catalog (REQ/RITM/SCTASK), approvals, Record Producers
- Day 4: Problem Mgmt: RCA methods, Known Error, linking to Change
- Day 5: Change Mgmt: models, CAB/ECAB, blackout windows, change failure prevention
- Day 6: Technical: Flow Designer vs Workflow, Notifications, BR/Client Script/UI Policy, ACL basics
- Day 7: Run 8–10 scenario drills + KPI story bank (MTTR, FCR, reopen rate, change failure rate)
Comment your experience level (0–2, 3–6, or 7+) and role target (Analyst/Admin/Process Owner), and I’ll suggest the highest-impact sections to revise first.
