Free AI Mock Interview Tool for English Speaking Practice — Quaesta

I Built a Free AI Mock Interview Tool — Here's Why

Preparing for a job interview is stressful enough. Preparing for one in a second language is harder still. As a developer who isn't a native English speaker, I kept running into the same wall: I could answer technical questions in my head, but speaking them out loud, under pressure, in English — that was the part no amount of reading could fix.

So I looked for tools to practice with. There are plenty. But almost every one of them had the same two problems: they cost money, and they buried the actual practice behind sign-up forms, onboarding flows, and endless configuration. I just wanted to upload my CV and start talking.

That's why I built Quaesta — a free AI mock interview tool that strips away everything except the part that matters: practicing real interview questions, out loud, and getting honest feedback.

What it actually does

The flow is deliberately short:

1. Upload your CV. The AI reads it and figures out your role and seniority level — a fresher and a senior engineer get very different interviews.
2. Get a real interview structure. Instead of a flat list of trivia, it builds an interview the way a real one flows: introduction, deep-dives into your actual projects, technical questions grounded in your stack, situational questions, and a wrap-up.
3. Answer by voice. Each question is read aloud, and you respond by speaking — just like a real interview. This is the part most tools skip, and it's the part that matters most for English practice.
4. Get scored feedback. When you finish, you receive a report with per-question scores and an honest summary of your strengths and gaps.

Why "less" was the whole point

Most interview-prep tools try to do everything. Quaesta does one thing: get you from "I need to practice" to "I'm practicing" in the fewest possible steps. There's no account to create, no credit card, no setup. You can start a real mock interview within seconds of landing on the page.

It's free, with a fair-use limit of 5 interviews per day — enough to practice seriously without me going bankrupt on API costs.

Who it's for

If you're a student, a fresher, or anyone preparing for a technical interview — especially in English as a second language — this is built for you. The AI adapts to your background, so whether you're interviewing for a backend role, data analysis, or something else entirely, the questions come from your experience, not a generic question bank.

I built this because I needed it. If you're in the same spot — knowing your stuff but needing to practice saying it out loud — I hope it helps you the way it helped me.
