How to practice for an interview when you have no one to practice with

“Just do a few mock interviews before the real one” is correct advice and also, for a lot of people, close to useless — because it quietly assumes you have someone available, willing, and honest enough to run one with you. A friend who'll actually push back instead of saying “yeah that sounded good.” An hour of their time, more than once, on your schedule. That's a real ask, and plenty of people don't have it to make.

If that's you, here's what actually helps, roughly in order of how much it costs you to set up.

1. Say the answer out loud.

This is the single highest-leverage thing you can do alone, and almost nobody does it. Reading a strong answer in your head feels like preparation. It isn't practicing the actual skill, which is producing speech, live, under time pressure. Pick a likely question, set a timer for ninety seconds, and speak your answer out loud — to an empty room, to your phone's voice recorder, it doesn't matter. The gap between what you meant to say and what actually came out of your mouth is the thing you're training. You will not find that gap by rehearsing silently.

2. Record yourself and watch it back once

Once is enough — past a certain point, re-watching your own footage just makes you self-conscious without teaching you anything new. What you're checking for on that one watch-through: did you answer the actual question asked, or the question you'd prepared for? Where did you hedge when you actually knew the answer? Where did the first sentence bury the point instead of leading with it?

3. Write down the real follow-up questions

A list of “common interview questions” only gets you halfway there, because the opener is rarely what determines the outcome — the follow-up is. “Tell me about a time you disagreed with a decision” is easy. “What would you have done if they'd said no?” is the one that actually tests whether you lived the story or are describing it secondhand. For each answer you prepare, write down the two hardest follow-ups a skeptical interviewer would actually ask, and work out a real, detailed answer to those too.

4. Get a second voice in the room, even an artificial one

The honest limitation of all three steps above is that you're still grading your own homework — you already know where your story is going, so nothing catches you off guard the way a real interviewer would. At some point you need something that actually pushes back, asks a follow-up you didn't plan for, and tells you plainly where the answer fell apart. That's the specific gap a live mock interview is built to close when there's no one around to run one with you — same pressure, same need to think on your feet, available at whatever hour you actually have free.

None of this requires a study group, a career coach, or a friend with an hour to spare. It requires saying the words out loud, watching yourself do it once, and finding something willing to ask the follow-up you didn't prepare for.
