Technical practice
How would you structure an AI-driven ServiceNow solution using App Engine and Scoped Apps?
What to coverSuggested preparation: Explain how you would separate application responsibilities, set architecture standards, and plan for maintainability across client engagements. Discuss trade-offs between reusable components and client-specific needs.
How would you design and troubleshoot a ServiceNow workflow built with Flow Designer and IntegrationHub?
What to coverSuggested preparation: Walk through workflow boundaries, integration dependencies, failure handling, and how you would diagnose a failed step. Explain how you would validate the workflow before production use.
How would you decide where Virtual Agent and Now Assist belong in a ServiceNow workflow?
What to coverSuggested preparation: Compare conversational interaction with AI assistance within an existing workflow, including when human review is appropriate. Describe how you would judge whether either feature improves the intended outcome.
How would you approach AI Search optimization versus a RAG-based solution?
What to coverSuggested preparation: Discuss retrieval relevance, source quality, and how retrieved information supports an answer or action. Explain how you would evaluate the trade-off before adding vector search or RAG to a ServiceNow use case.
How would you integrate an LLM and evaluate prompts for a production ServiceNow feature?
What to coverSuggested preparation: Cover prompt design, representative test cases, and measures of answer quality and failure. Explain how evaluation results would guide changes before and after release.
When would an agentic pattern be appropriate in a ServiceNow workflow?
What to coverSuggested preparation: Distinguish a multi-step, orchestrated approach from a simpler workflow or single LLM call. Address action boundaries, human oversight, and how you would contain unintended actions.
How would you design a secure integration between ServiceNow and an external service?
What to coverSuggested preparation: Explain how you would choose an appropriate REST or SOAP integration pattern and when MID Server is relevant. Discuss authentication considerations for OAuth or SAML, failure handling, and verification of the data exchanged.
What governance and Responsible AI controls would you apply to an AI feature?
What to coverSuggested preparation: Describe how you would define security, compliance, and review requirements as architecture decisions rather than late-stage checks. Explain how you would assess risks and document the controls chosen for a client use case.
What would you monitor when an AI-driven ServiceNow feature is live?
What to coverSuggested preparation: Cover operational health, model or response quality, and signals that a feature is no longer meeting its intended outcome. Explain how observability would help you investigate failures and decide whether to revise or restrict the feature.
How would you validate that an AI-driven solution is ready to ship?
What to coverSuggested preparation: Describe checks for functional quality, AI evaluation, security, compliance, and operational readiness throughout the engineering lifecycle. Explain how you would connect release decisions to measurable business outcomes without treating a working demonstration as sufficient evidence.
Behavioural practice
Tell me about a time you owned delivery across competing client priorities.
What to coverSuggested preparation: Use situation, action, and result to explain how you set priorities, coordinated delivery, and handled trade-offs. Include the outcome measures you used, if available.
Describe a discovery workshop that changed your proposed solution or roadmap.
What to coverSuggested preparation: Use situation, action, and result to show how you uncovered business priorities and translated them into decisions. Explain how you communicated the resulting roadmap to stakeholders.
Tell me about a time you coached a cross-functional agile team through a delivery challenge.
What to coverSuggested preparation: Use situation, action, and result to describe the team's challenge, your coaching or management actions, and the effect on delivery. Be clear about your own contribution rather than attributing all team work to yourself.
Describe a time you influenced stakeholders to adopt a new engineering approach.
What to coverSuggested preparation: Use situation, action, and result to explain the proposed change, concerns raised, and how you built agreement. Connect the outcome to sustainable adoption rather than novelty alone.
Tell me about a time you negotiated a delivery decision where risk and speed conflicted.
What to coverSuggested preparation: Use situation, action, and result to show how you explained the trade-off, involved the relevant decision-makers, and managed the risk. Describe what was decided and what you learned from the result.
