Phone screen

  1. 1Tell me about a feature you built from database to UI.
  2. 2Where do you naturally gravitate — frontend or backend — and where do you stretch?
  3. 3How do you scope an ambiguous feature request into shippable work?

Technical

  1. 1How do you decide what logic belongs on the client vs. the server?
  2. 2Walk through how you'd model data and APIs for a commenting feature.
  3. 3How do you keep a full-stack codebase maintainable as it grows?
  4. 4What's your testing strategy across the stack?

Behavioral

  1. 1Describe a time you shipped something fast and had to clean it up later.
  2. 2How do you collaborate with PMs and designers on scope?

Situational

  1. 1A feature is half-built and priorities shift. How do you decide what to do with it?
  2. 2You're the only engineer on a feature with a tight deadline. How do you de-risk it?
