Technical practice
How would you structure an AI-enabled feature in a ServiceNow scoped application?
What to coverPreparation suggestion: Explain how the data model, application scope and platform components would fit together. Discuss maintainability and access boundaries without assuming a particular client implementation.
When would you use a Business Rule, client script or UI policy?
What to coverPreparation suggestion: Compare server-side logic with client-side behaviour and explain where each is appropriate. Describe how you would avoid conflicting logic and test the resulting behaviour.
How would you automate a ServiceNow workflow using Flow Designer and IntegrationHub?
What to coverPreparation suggestion: Walk through a plausible workflow, including its trigger, actions, external connection and failure handling. Explain how you would decide what belongs in a flow versus custom JavaScript.
How would you configure and validate a Now Assist feature?
What to coverPreparation suggestion: Describe how you would define the feature's intended task and check the usefulness and accuracy of its outputs. Address access to underlying data and what should happen when the output is unsuitable.
How would you design a Virtual Agent interaction?
What to coverPreparation suggestion: Explain how you would define the user's goal, conversation paths and handoff or fallback behaviour. Describe how you would test whether the interaction completes the intended task.
How would you tune AI Search, and when might RAG help?
What to coverPreparation suggestion: Distinguish search relevance from generating an answer grounded in retrieved content. Discuss basic retrieval checks, including whether the right content is available and whether an answer reflects it.
How would you write and evaluate prompts for a ServiceNow AI feature?
What to coverPreparation suggestion: Explain how you would specify the task, context, output constraints and representative test cases. Compare possible evaluation measures such as task success, accuracy and unsafe or unsupported responses.
Where could an agentic pattern help with workflow automation or developer assistance?
What to coverPreparation suggestion: Describe a bounded task an agent could perform and what tools, permissions and checkpoints it would need. Weigh automation benefits against incorrect actions and the need for human review.
How would you approach a ServiceNow integration that requires authentication?
What to coverPreparation suggestion: Compare REST and SOAP at a high level, and explain when a MID Server might be relevant. Discuss how you would investigate an authentication or connectivity failure involving OAuth or SAML without exposing credentials.
What checks would you make before shipping an AI-enabled ServiceNow feature?
What to coverPreparation suggestion: Cover functional testing, AI-output evaluation, secure engineering and Responsible AI risks. Explain how code review and repeatable tests could help maintain quality and compliance as the feature changes.
Behavioural practice
Tell me about collaborating with product and architecture stakeholders on a feature.
What to coverPreparation suggestion: Use a real situation to explain the differing priorities, your actions to clarify decisions and the result. Highlight how you communicated trade-offs during iterative delivery.
Describe a code review that changed your approach.
What to coverPreparation suggestion: Give the situation, the feedback or disagreement, the action you took and the result. Focus on how the exchange improved quality or maintainability rather than on winning an argument.
Tell me about diagnosing a difficult software defect.
What to coverPreparation suggestion: Describe the symptoms and constraints, the steps you took to isolate the cause and the result. Show attention to detail, including how you checked that the fix worked.
Describe a time you had to learn an unfamiliar technology quickly.
What to coverPreparation suggestion: Explain the situation, how you identified what you needed to learn, what you applied and the result. Keep the example tied to delivering useful work rather than listing topics studied.
Tell me about adapting when a client-facing requirement changed.
What to coverPreparation suggestion: Outline the original goal, what changed, how you reprioritised or communicated the impact and the result. Explain how you protected quality while responding to the change.
