What each round is testing
| Round | What they want to learn | How to prepare |
|---|---|---|
| Screening | Can you communicate, and do you roughly fit the role? | A one-minute answer to "Tell me about yourself", and why this job |
| Technical | Can you reason through a problem and explain it? | Think out loud; state assumptions; test your own answer |
| Project deep dive | Did you really build what your CV says? | Know every decision in one project and what you would change |
| Panel | How do you work with people and handle pressure? | Two or three short stories: a problem, a disagreement, a mistake |
A two-week plan
- Days 1 to 2: read the job. List the skills it names. Mark the ones you can show with a project, and the ones you can only talk about.
- Days 3 to 5: one project, in depth. Pick the project closest to the job. Be ready to explain its structure, one hard bug and one trade-off.
- Days 6 to 9: fundamentals. Revise the core topics for the role with active recall, not re-reading. See Active recall and flashcards.
- Days 10 to 12: say your answers out loud. Practise the common questions spoken, not written, and time them. Aim for about a minute each.
- Days 13 to 14: a full mock. Run a complete interview under time, then fix the single weakest answer.
Talking about your projects
The strongest answer to almost any technical question is a real example. Use this shape: what the project does, what you built yourself, one problem you hit, how you found the cause, and what you would do differently. If you used AI to write parts of it, be ready to explain those parts too. An interviewer who finds code you cannot explain will assume the rest is the same.
If you inherited or generated much of your code, How to understand AI-generated code is worth reading before the interview.
