Q: How does ACL (Access Control List) work?
A: ACLs restrict access to records or fields using conditions, roles, and script evaluation.
Q: What is a business rule?
A: Server-side scripts triggered on record insert, update, delete, or query for automation.
Q: How do you troubleshoot a slow-running list in ServiceNow?
A: Check indexing, filters, query conditions, ACLs, and client scripts; use the Performance Analytics.
Scripting & Development
Q: What is GlideRecord?
A: A server-side API to query and manipulate ServiceNow records programmatically.
Q: When do you use client scripts vs UI policies?
A: Use client scripts for complex logic; UI policies for simple show/hide/mandatory behaviors.
Q: What is a Script Include?
A: Reusable server-side JavaScript functions callable from other server scripts or via REST.
Q: How do you secure scripts that run in the browser?
A: Limit exposed data, use GlideAjax for server-side processing, validate inputs server-side.
Q: Explain a Business Rule vs Workflow decision.
A: Business Rules run server-side code; Workflows orchestrate visual multi-step processes and approvals.
CMDB & Integrations
Q: What is CMDB and why is it important?
A: Configuration Management Database holds CI data for IT services, enabling impact analysis and change planning.
Q: How do you import data into the CMDB?
A: Use Import Sets, Transform Maps, and identification rules to map source fields to CI classes.
Q: What is MID Server and when is it used?
A: A local agent for discovery, integrations, and accessing on-prem resources securely.
Q: How do you handle duplicate CIs in CMDB?
A: Use identification/discovery rules, merge duplicates, and maintain reconciliation logic.
Q: Describe a common integration approach with REST and SOAP.
A: Use RESTMessageV2 for REST, SOAPMessageV2 for SOAP, authenticate securely and map payloads in scripts.
ITSM Process & Platform Features
Q: How would you design an Incident to Change workflow?
A: Define triggers, approvals, risk checks, and automated tasks; connect Incident updates to Change records via business rules.
Q: Explain SLA configuration and breach notifications.
A: SLAs use conditions and timers to track targets; configure notifications and escalation rules on breach.
Q: What is Service Catalog and how do you maintain it?
A: A user-facing set of catalog items and workflows; manage via catalog tasks, variables, and approval flows.
Q: How do you manage upgrades and customizations?
A: Limit scoped customizations, document update sets, test in sub-prod instances, and follow upgrade review best practices.
Q: How do you monitor instance health?
A: Check system logs, performance dashboards, scheduled jobs, and use baseline metrics to detect regressions.
Troubleshooting & Real-World Scenarios
Q: How do you approach a user-reported form error?
A: Reproduce, review client scripts/UI policies/ACLs, check console/server logs, apply a minimal fix and test.
Q: Describe handling a production outage caused by a recent change.
A: Roll back update set or disable change, notify stakeholders, perform root-cause analysis, and implement a fix.
Q: How do you tune a slow-running Business Rule?
A: Review query efficiency, limit GlideRecord calls, add indexing, and move logic to asynchronous jobs if needed.
Q: What steps do you take for data privacy in ServiceNow?
A: Apply field encryption, ACLs, data policies, and audit logs; follow company governance and compliance controls.
Q: Tell me how you'd document a handover to support teams.

A: Clear documentation, proactive monitoring, strong communication, and a focus on measurable outcomes.
How to prepare effectively for a Servicenow Administrator/support interview?
Short answer: combine hands-on practice, scenario-based storytelling, and platform knowledge checks.
Preparation should include lab time on a personal developer instance, rehearsing 30-second technical explanations, mapping two or three impactful project stories for behavioural questions, and reviewing common troubleshooting patterns. Use community Q&A threads and curated lists of questions to simulate interviews. Takeaway: prioritize show-and-tell examples that prove both technical depth and operational impact. For curated question sets and community insights, review guides from S2-Labs and Mindmajix resources.
