Mastering ServiceNow ITSM interviews requires a deep understanding of Incident Management, Problem Management, Change Enablement, Service Catalog item variables, and SLA definition engines. Below are 15 high-frequency technical questions asked by enterprise lead architects.
Q1: Explain the difference between Incident and Problem Management in ITIL and ServiceNow.
Answer: Incident Management focuses on restoring normal service operation as quickly as possible with minimal disruption (workarounds allowed). Problem Management focuses on identifying the root cause of one or more recurring incidents to permanently eliminate the defect.
Q2: How does the SLA Engine calculate Breach Time in ServiceNow?
Answer: The Task SLA engine monitors Task SLA records created from Task SLA Definitions. It calculates breach time based on target duration, start/pause/cancel conditions, and the schedule attached to the SLA record (e.g. 8×5 Workdays vs 24×7 Coverage).
