Most mistakes are about the format, not the answers
People who do well in a normal interview sometimes stumble in an AI one. The questions are usually familiar. What trips them up is the format: a timer, no reactions, a camera, and a recording they can't take back. The good news is that most of these mistakes are easy to fix with a little rehearsal.
If you are new to the format, our explainer on what an AI interview is is a good place to start.
Reading a script
It is tempting to write every answer out and read it off the screen. It shows. Your eyes move side to side, your voice goes flat, and the answer sounds like a recital. A reviewer watching the recording notices straight away.
Fix: write stories as four short lines, one each for situation, task, action and result, and speak from those. The STAR method gives you the four lines. Rehearse until you only glance at them.
Answering the question you prepared for
You have a great story about a deadline. The question asks about a disagreement. You tell the deadline story anyway. In a transcript, the mismatch is plain.
Fix: start every answer by echoing the question in your own words. 'A disagreement I handled was…' forces you to pick a story that fits. If none does, adapt the closest one and say which part answers the question.
Running out of time
Long setups are the most common way to lose the result. A minute on background, thirty seconds on what you did, and the timer ends before you say what happened.
Fix: practice with a timer set to the real limit. Aim to reach your actions within the first twenty seconds. If the interview gives you two minutes, finish at about a minute and a half. Our recorded interview rehearsal post has a timer drill.
Saying 'we' the whole time
Teamwork is good. But if every sentence starts with 'we', the reviewer can't tell what you did.
Fix: in practice, count your 'I's. Credit the team once, then describe your own decisions and actions.
We noticed the reports were late, so we changed the process and it worked.
Our reports kept going out late. I mapped where the delays were, saw that approvals sat in one inbox, and proposed a shared queue. My manager agreed, and the reports went out on time from the next month.
Skipping the tech check
A muffled microphone, a camera pointed at the ceiling, a browser that blocks permissions. These are fixable in ten minutes the day before and impossible to fix mid-answer.
Fix: do the platform's practice question on the same device, browser and spot you will use. The setup post in this series covers camera, lighting and sound in detail.
Treating silence as failure
With no one nodding, many people speed up, over-explain or trail off waiting for a sign. Then they assume they did badly.
Fix: plan your last line, something like 'and that's how it worked out', so you know when you're done. Pause, breathe, move on. Our post on feeling nervous about an AI interview has more on getting used to the quiet.
Not practicing out loud at all
Most of the mistakes above only show up when you speak. Reading answers silently feels like practice, but it skips the part that goes wrong.
Fix: record yourself answering three questions, then listen back. Or rehearse with someone who asks and waits. If you want an AI interviewer that asks about your own résumé and a coach review that points at the weak answer, Hmmlo does that. Either way, say the answers before the day.
