About your past
Tell me about a time you set engineering standards for a team. How did you get developers to follow them?
What they are checking: Whether they drive engineering excellence through example, review and tooling rather than decree.
Tell me about a production issue you led the team through. What did you change afterward?
What they are checking: Calm hands-on leadership in incidents and a habit of fixing root causes.
What would you do
A business stakeholder wants a feature in two weeks that you think needs six. How do you handle that?
What they are checking: Negotiating scope honestly and offering options rather than overpromising or flatly refusing.
How much of your week do you expect to spend writing code versus reviewing and guiding others, and why?
What they are checking: Whether they truly want a hands-on lead role and can balance their own output with multiplying the team.
A junior developer's pull request works but is hard to follow. How do you give that feedback?
What they are checking: Ability to coach through code review in a way that improves skills without discouraging people.
About the work
You'd lead engineering for the Client Onboarding and Lifecycle Management portfolio. What makes onboarding software hard to get right at a bank?
What they are checking: Awareness of KYC, document handling, workflow state and audit trails that make CLM more than a simple form app.
Walk me through how you'd design a full stack onboarding workflow that can pause for compliance review and resume days later.
What they are checking: Ability to design durable, stateful workflows with clear data models, APIs and front-end handling of long-running processes.
How do you approach security in a web application that handles client identity documents and personal data?
What they are checking: Practical knowledge of authentication, authorization, input validation, encryption and secrets handling in sensitive apps.
How do you keep a front end fast and maintainable as a product grows over several years?
What they are checking: Judgment on component structure, state management, testing and performance budgets for long-lived apps.
How do you design APIs between the onboarding front end and back-end systems so other teams can rely on them?
What they are checking: Thinking about contracts, versioning, error handling and documentation for scalable, shared services.
