How do I do a mock interview by myself?

Use a practice partner that reacts — a friend with your question list, or an AI interviewer. Record it, keep to time, and review once against a short checklist rather than re-listening repeatedly.

How long should a mock interview be?

Ten to twenty minutes is plenty. Frequency beats duration.

Should I mock interview the day before?

Do a short, easy run the day before to build confidence, and leave the hard critical work three or more days out.

Mock interviews that behave like the real interview

A mock interview is only useful if it is uncomfortable in the same way the real one will be: spoken aloud, timed, with follow-up questions and no chance to rewrite your answer. Anything gentler measures your reading, not your interviewing.

What separates a useful mock interview from a comfortable one

It is spoken, start to finish, with no pausing to compose an answer.
The interviewer stays in role even when you struggle.
It includes at least two follow-ups per answer.
It ends with specific feedback tied to moments, not general encouragement.
You repeat it. One mock interview is a diagnosis; the second is the practice.

Rounds worth mocking separately

1Screening callShort, energy matters, and "why this role" carries most of the weight.
2Behavioural roundStories with results. Expect "what would you do differently?"
3Technical or case roundThink out loud on purpose; silence reads as being stuck.
4Final round with a senior leaderFewer questions, more judgement. Be concise and have questions of your own.

Self-review checklist after each mock

Did I answer in the first sentence?
Did every story include a result someone else would notice?
How many times did I say "kind of" or "I guess"?
Where did I speed up, and what was I anxious about there?
What did I ask them?
