Common interview questions to practise

Careers Updated Oct 10, 2026

  • Tell us about yourself (60–90 seconds, focused on what you build).
  • Walk us through a project you are proud of.
  • How do you debug something that works locally but not on the server?
  • What is the difference between let, const and var? What does async/await do?
  • How would you design a table for students, courses and enrolments?
  • How do you keep a REST API secure (authentication, validation, rate limits)?
  • Describe a time you received critical feedback on your code.

Use the practice quizzes in your courses and the AI study assistant (if enabled) to rehearse explanations.
