How to practice
- Read the question and answer it out loud before you look. Time yourself: aim for about a minute.
- Compare with the model answer. Note what you missed, then say it again in your own words.
- Answer the follow-up. Interviewers usually push one level deeper, and that's where answers fall apart.
- Swap in an example from your own work. A real system you built beats any textbook example.
- Want every model answer? Each page's answers come as a free PDF.
