Interview questions
- Walk me through a feature you built end to end, from the database to the UI. What would you design differently now?
- A page that used to load in one second now takes eight. How do you find out why?
- Tell me about the hardest bug you have tracked down. How did you finally find it?
- How do you decide what to test, and what not to test, on a new feature?
- You disagree with a teammate about how to structure an API. How do you resolve it?
What a strong answer shows
- Explains trade-offs, not just the stack used.
- Measures before guessing: profiling, network, database queries.
- Describes a method for narrowing the cause, not luck.
- Tests the parts that would hurt most if they broke.
