Sample interview questions
I would explain how I clarified the customer problem and acceptance criteria, decomposed the work into deliverable increments, identified technical risks, and aligned with product and QA. I would then describe implementation, testing, rollout monitoring, and how customer or product feedback informed follow-up improvements.
I would begin by defining the workload, consistency requirements, failure modes, and service boundaries. I would use Elixir and OTP supervision principles for fault tolerance, design clear domain interfaces, instrument key operations, and use asynchronous processing where appropriate while preserving transactional correctness for critical workflows.
I use well-defined component boundaries, typed and documented GraphQL operations, reusable UI patterns, and explicit loading and error states. I also avoid over-fetching, keep server and client ownership clear, test critical user paths, and regularly simplify components or queries that become difficult to reason about.
I first reproduce or observe the issue using production-safe telemetry, query plans, and relevant workload data. I verify indexes, join strategy, filtering, pagination, and data-access patterns, then make a targeted change and measure the result while watching for regressions in correctness or write performance.
I set clear expectations, provide context rather than only answers, and break work into ownership-sized tasks with appropriate review checkpoints. In code reviews and pairing sessions, I focus on explaining tradeoffs, reinforcing quality standards, and gradually increasing independence while protecting project timelines.
