ServiceNow Administrator Interview Questions for Hiring

Introduction

In most organizations, ServiceNow changes affect more than a single team. A small configuration update can influence approvals, forms, workflows, reporting, and connected systems across the business. That makes the ServiceNow Administrator role important for maintaining platform stability while ensuring updates, customizations, and releases are introduced in a controlled and scalable way.

When interviewing candidates for this role, hiring teams should assess how they manage configuration changes, reduce upgrade risk, troubleshoot platform issues, and support ongoing governance. These ServiceNow Administrator interview questions are designed to help evaluate those capabilities across different experience levels, including pre-screening video interview questions for early candidate assessment.
