Role-specific / technical competencies

  1. Walk us through the architecture of a system you built recently. What trade-offs did you make?
  2. How do you decide how much test coverage a feature needs before shipping it?
  3. Describe a production incident you debugged. How did you find the root cause?
  4. How do you approach code reviews, both giving and receiving feedback?
  5. What do you do when requirements are ambiguous or incomplete?

Behavioural & culture fit

  1. Tell us about a time you disagreed with a teammate on a technical decision. How was it resolved?
  2. Describe a situation where you had to deliver under a tight deadline. What did you cut and why?
  3. How do you keep your skills current, and what have you learned recently?

Problem-solving / case

  1. A feature you shipped last week is causing intermittent errors for 2 percent of users. How do you investigate?
  2. You inherit a legacy codebase with no tests and a critical bug. What are your first steps?
