WATCH OUT

5 Mistakes That Cost Generative AI Candidates the Job

Interviewers watch for these red flags — not just knowledge gaps.

Memorising Without Understanding

Candidates who memorise answers without understanding concepts fall apart when interviewers ask follow-up questions.

Fix: Understand the why behind every answer

No Real-World Examples Ready

Saying 'I know this' without a concrete example is a red flag. Interviewers want applied knowledge not just theory.

Fix: Prepare one real example per concept

Ignoring Edge Cases

Only answering the happy path shows shallow thinking. Interviewers test if you think about what can go wrong.

Fix: Always ask yourself what could fail

Freezing Under Pressure

Silence is worse than saying 'Let me think through this'. Composure and structured thinking matter as much as the answer.

Fix: Practice thinking aloud every day

Never Testing Their Readiness

Most candidates feel ready but have never actually measured themselves. The gap you don't know about is the most dangerous.

Fix: Take the free assessment before your interview
