Technical practice
How would you structure a ServiceNow feature using JavaScript, Business Rules, client scripts, and UI policies?
What to coverSuggested preparation: Explain which logic belongs on the server versus the client, how it interacts with the data model, and how you would avoid conflicting behavior. Discuss how a Scoped Application affects design and testing.
How would you configure and validate a Now Assist feature?
What to coverSuggested preparation: Walk through the intended user task, configuration choices, and checks for useful, accurate output. Explain how you would handle responses that are incorrect or inappropriate before release.
How would you design a Virtual Agent interaction for a ServiceNow workflow?
What to coverSuggested preparation: Describe how you would guide the user, collect needed information, and connect the interaction to the workflow. Address testing for unclear requests and unsuccessful outcomes.
How would you assess and tune AI Search results?
What to coverSuggested preparation: Define what a relevant result means for a user task and how you would compare results before and after a change. Discuss trade-offs between broad coverage and precise results.
When would you use App Engine Studio, Flow Designer, or IntegrationHub in a feature?
What to coverSuggested preparation: Compare their roles in building an application, automating a workflow, and connecting another system. Explain how you would choose an approach that remains maintainable and testable.
How would you troubleshoot a ServiceNow integration that is failing?
What to coverSuggested preparation: Trace the request, authentication, connectivity, and response before changing code. Be ready to distinguish where REST or SOAP, MID Server, OAuth, or SAML may be relevant without assuming every integration uses them.
How would you apply an agentic pattern to workflow automation or developer assistance?
What to coverSuggested preparation: Describe how tasks, tool use, and stopping conditions could be bounded. Explain when a simpler deterministic workflow would be preferable and how you would validate the agent's actions.
How would you write and evaluate a prompt for an AI-enabled feature?
What to coverSuggested preparation: Explain how the prompt specifies the task and constrains output, then identify evaluation criteria suited to that task. Discuss how representative test cases and failure analysis would guide revisions.
What would you consider when adding retrieval-augmented generation to a ServiceNow solution?
What to coverSuggested preparation: Explain retrieval, vector search, and how retrieved content could inform a response. Discuss source relevance, stale or missing information, and tests that distinguish retrieval failures from generation failures.
How would you decide whether an AI-enabled feature is ready for production?
What to coverSuggested preparation: Cover functional testing, AI evaluation, security, Responsible AI, and compliance considerations stated in the role. Explain how you would investigate failures and use findings to improve the feature after release.
Behavioural practice
Tell me about a time you aligned technical work with architects or product owners.
What to coverSuggested preparation: Give the situation, your actions to clarify requirements or trade-offs, and the result. Make your contribution to a shared decision clear.
Describe a code review in which you improved quality or changed your approach.
What to coverSuggested preparation: State the context, the feedback you gave or received, the action taken, and the result. Explain how you handled disagreement constructively.
Tell me about a difficult defect you investigated.
What to coverSuggested preparation: Describe the symptoms, how you narrowed down the cause, the fix or mitigation, and the result. Highlight the evidence you used rather than assuming the first explanation was correct.
Describe a time priorities changed during a sprint or client-focused delivery.
What to coverSuggested preparation: Set out the situation, how you communicated and adjusted your work, and the outcome. Include any trade-off you raised to protect quality.
Tell me about a time you learned an unfamiliar capability to solve a work problem.
What to coverSuggested preparation: Explain the need, how you learned and tested the capability, and the result. Distinguish what you verified from what remained uncertain.
