Sample interview questions
Describe a complex SaaS feature you owned from initial scope through production release.

I would explain how I clarified the customer problem and success criteria, decomposed the work into deliverable milestones, aligned technical trade-offs with product and QA, and monitored the release after deployment. I would include measurable outcomes such as improved workflow completion, performance, reliability, or reduced support volume.

How would you design a scalable Elixir service that supports a React application and GraphQL API?

I would use clear domain boundaries, supervised processes for fault tolerance, well-defined contexts, and efficient database access patterns. For GraphQL, I would avoid N+1 queries through batching or dataloading, enforce authorization at resolver boundaries, and expose stable API contracts for the React client.

What approach do you take when diagnosing a slow relational-database query in production?

I start by reproducing or measuring the issue with query timing, execution plans, and relevant application telemetry. I then assess indexes, joins, filtering, data volume, and ORM-generated queries, make the smallest safe improvement, validate the plan and results, and monitor performance after release.

How do you handle ambiguity or scope changes while owning a project?

I make assumptions explicit, identify the customer and technical risks, and propose options with cost and impact estimates. I facilitate a decision with product stakeholders, update the delivery plan, and communicate progress and trade-offs regularly so the team is not surprised.

How do you mentor junior engineers while maintaining delivery momentum?

I provide context rather than only answers, use code reviews to explain principles and trade-offs, and create appropriately scoped ownership opportunities. I pair on difficult work when needed, set clear quality expectations, and progressively increase autonomy while protecting deadlines and production quality.
