How to Prepare for an AI Interview — From Someone Who Builds Them

The invite said “AI interview, optional.” A legit company. A real role. And a robot on the other end of the call. I booked it out of curiosity — I'd honestly thought the AI-interview panic was overblown, and I wanted to see one from the candidate's side of the table, because I've built an AI mock interviewer myself. The second the voice started, I recognised the voice provider. I knew the stack. I knew, roughly, what was happening under the hood.

It still threw me. The thing machine-gunned questions at me. No pauses. No reactions. No “tell me more about that.” Question, answer, next question, next question. And the strangest part wasn't the robot voice — it was knowing, the whole time, that I was being transcribed, summarised and scored, with no idea what for. Was it grading my tone? My filler words? Whether I sounded confident? No clue.

So here's where I've landed, and I'll say it plainly: AI interviews are going to become normal. That ship has sailed. Arguing about whether they should exist is a waste of breath at this point. The argument worth having is the one almost nobody is having — how do you actually prepare for one? Because preparing for an AI interview the way you'd prepare for a human one is how good candidates end up with bad transcripts. Plenty of people are just tired of the whole format, and honestly, fair. Be tired. But be tired and prepared, because this format punishes people who wing it in very specific, very fixable ways.

Stop saving material for follow-up questions. There aren't any.

With a human interviewer, the smart move is to give the short version and let them pull the thread. You say, “the project got messy and I ended up owning the cleanup,” and they lean in and ask what happened. That back-and-forth is where you shine. It's also, weirdly, a trap now — because most AI interviewers don't pull threads. They ask. They listen. They move on. Whatever you didn't say? It doesn't exist.

So front-load everything. Treat every question as your only shot at that topic. A self-contained answer has a simple shape: here's the situation, here's what I did, here's what happened because of it. Concrete version — the bot asks: “Tell me about a time you dealt with a difficult stakeholder.”

End your answers like you mean it

These systems generally decide you're finished when you stop talking. Which sounds obvious until you realise what it does to people who trail off. If your natural ending is “…so, yeah, that was that, I guess…” — the system either cuts you off mid-mumble or faithfully records the mumble. Neither helps you.

The fix is almost stupid: script your landing. Pick a closing move and use it every time. End on the result — “—and that's what we shipped” — then stop. Full stop. Don't fill the silence.

With a human, silence is a social cue, and filling it is polite. With a bot, silence is a button. Everything you say while nervously waiting for a reaction gets transcribed as part of your answer — and there is no reaction coming.

You're being read, not heard — so write for the transcript

This was the part that unsettled me most in my own AI interview: knowing my words were becoming a document I'd never see, scored against a rubric I'd never see. You're allowed to be annoyed by that — I am — and you should still use it.

Whatever scores you is working from a transcript or a summary of one. So make your answers easy to summarise. Echo the language of the question: if it asks about conflict, say the word “conflict” — don't drift into a vague story about “friction with a colleague” and hope the model connects the dots. Name your outcome in plain words: “the result was,” “what changed was.” You're not writing poetry. You're making sure a summarising model can't miss your point.

Practise against something that doesn't react

Practising with a friend rehearses exactly the skill AI interviews remove: reading the room. Your friend nods. Their face does things. You calibrate off it constantly without noticing. Then the bot gives you nothing, and the silence where feedback should be is what makes people ramble. Talking to an AI is not the same as talking to a human. Candidates who prep for one and get the other struggle — that's the whole trap, and it's avoidable.

So rehearse the real conditions. Use an AI mock interviewer if you can get your hands on one — that's the closest match to the real thing. And the no-tools version works too, awkward as it is: write questions on cards, sit alone in a room, start a timer, and answer out loud to nobody. No nods. No cues. No “mm-hm.” It feels ridiculous. That's the point — the ridiculousness is the format, and you want to have met it before it counts.

The part nobody's owning up to

I'll state my position plainly, because pretending to be neutral here would be dishonest. Being scored by a black box on your tone, your confidence and your filler words — with no idea of the rubric — is the genuinely rotten part of all this, and vendors are quiet about it. Not the robot voice. The robot voice is just uncanny. The invisible rubric is unfair.

And the frustrating twist, wearing my builder hat: it doesn't have to be this bad. Current conversational AI can pause. It can react. It can ask “tell me more.” Most hiring bots use a fraction of what the tech can actually do — the machine-gun experience is a design choice, not a technical limit. Somebody shipped that and called it done.

But you don't get to pick which version greets you on the call. So expect the dumb one. Prep for the dumb one. If you happen to get a good one, you'll be pleasantly over-prepared — which is the best kind of surprised. Would I book that optional AI interview again, knowing all this? Yeah. I'd rather meet the machine on purpose, on a low-stakes day, than for the first time when it actually matters.
