About the role
A full-stack engineer builds complete features, from the screen a user taps to the API and database behind it. Day to day you move between front end work, backend logic, data changes and deployment, often owning a feature from idea to release. The panel is checking that you are solid on both sides and can make sensible calls about where logic should live.
How to prepare
- Choose one feature you built end to end and be ready to explain every layer, from the form to the database table.
- Revise how authentication and sessions work across the browser and the server.
- Prepare an example where you chose between doing work on the client or the server, and explain why.
- Think about how you test a feature across layers so a change on one side does not quietly break the other.
- Be honest with yourself about your stronger side and prepare to show how you cover the weaker one.
Common mistakes
- Being shallow everywhere and unable to go deep on any single layer when pushed.
- Ignoring data design and treating the database as an afterthought.
- Describing features by the tools used rather than the user problem they solved.
