How Many Mock Interviews Should You Do Before the Real One?

People want a number — “do five and you're ready.” But the real answer isn't a count; it's a feeling you're aiming for, and the count is just how you get there. That said, let's give you both.

The principle: practise until it's boring

You're ready when the interview stops feeling novel — when “tell me about yourself” triggers a calm, rehearsed response instead of a spike of adrenaline. That's the target. Nerves are highest at first exposure and fall with repetition, so you're doing reps until the situation feels familiar, not until you hit an arbitrary milestone.

A rough guide

• If you haven't interviewed in years: more, not fewer. The rust is real. A handful of full reps to knock it off before anything that counts.
• If you interview semi-regularly: a couple of tune-ups to sharpen stories and shake off nerves.
• For a specific high-stakes interview: enough that you've rehearsed the likely questions out loud and re-run the ones you fumbled at least once.

For most people that lands somewhere in the small handful, not one and not thirty.

Quality over count

Three focused, out-loud, feedback-driven mocks beat ten you half-paid-attention to. A rep only counts if it's realistic enough to trigger the nerves and you actually act on the feedback. Ten passive run-throughs where you never review what went wrong is just ten chances to rehearse your mistakes.

How to know you're ready

Two signs: your core answers come out smoothly without scripting, and the thought of the interview produces mild anticipation rather than dread. When you hit those, you've done enough — whatever the number turned out to be.
