How I built an AI interviewer as a side project

My friend bombed an interview last year. Not because he wasn't good enough — he just had no one to practice with.

He'd spent weeks tailoring his CV, writing cover letters, researching the company. He was prepared on paper. But the moment he sat in that room, the questions caught him off guard. He rambled. He blanked. He didn't get the job.

The problem wasn't his experience. It was that he'd never actually said his answers out loud to someone who pushed back.

Interview coaching exists. But it costs £200 an hour and you need to book it three weeks in advance. Most people just wing it and hope for the best.

So I built Sarah.

Sarah is an AI interviewer. You paste in the job description, tell her your background, and she runs the interview. She asks real questions tailored to your role and seniority. She reacts to your answers. She follows up when something isn't clear. And when it's over, she gives you a scorecard — communication, confidence, structure, and exactly what to improve before the real thing.

She's available at 2am the night before your interview. She doesn't judge. She doesn't get bored. And she doesn't charge £200 an hour.

We also built CV tailoring — paste a job description and get your CV rewritten to match it in 60 seconds. But honestly, Sarah is the one people keep coming back for.
