Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time a production bug slipped through your tests. What did you change afterward?
What they are checking: Whether they learn from escapes by improving tests and pipelines, not just by fixing the single bug.
How do you review a teammate's pull request, and what do you look for first?
What they are checking: Whether their code reviews improve design and correctness while keeping teammates willing to ask for feedback.
What would you do
A product manager asks for a feature that would require a shortcut in security to hit the date. What do you do?
What they are checking: Whether they protect security in a healthcare setting while still offering a path to deliver value on time.
An API you own has slowed down as data volume grew. How would you find and fix the bottleneck?
What they are checking: Whether they diagnose performance with measurements across layers rather than guessing and rewriting code.
About the work
Walk me through a feature you built end to end with React, TypeScript and Node.js, from the database up to the UI.
What they are checking: Whether they can own every layer of a feature rather than handing off the parts outside their comfort zone.
How do you design a relational data model for an analytical workflow that will grow in ways you can't predict yet?
What they are checking: Whether they balance normalization, query performance and flexibility when the data model supports business analytics.
How would you integrate an LLM or agentic workflow into an existing web application safely?
What they are checking: Whether they handle latency, failures, prompt injection and data exposure when wiring AI into a real product.
What do you do to make a React component library accessible, and how do you test it?
What they are checking: Whether accessibility is part of their definition of done rather than something a later audit finds.
Explain how you'd set up authentication and authorization for an app that serves different health system clients.
What they are checking: Whether they understand tenant isolation and role-based access well enough to keep one client's data from another.
What logging, monitoring and tracing would you add to a new service before it goes to production?
What they are checking: Whether they build observability up front so problems can be found in minutes rather than days.
