Why we built an AI mock interview platform

Good interview practice shouldn't depend on who you know or what you can pay. Why we built RoundReady and what an AI interviewer does well.

Most people who land a top job had a lot of practice before the real round. Not reading. Practice. Someone across the table asking a question, waiting, then pushing on the weakest part of the answer.

The trouble is where that practice comes from. If you have friends already in consulting or a university society with alumni who'll give up their evenings, you get it. If you don't, you pay a coach by the hour or you go in having rehearsed alone. We built RoundReady because that felt like the wrong thing to decide who gets hired.

Reading about interviews isn't the same as doing one

There's no shortage of material. Frameworks, question banks, worked answers. You can read every one and still freeze when someone says “walk me through it” and goes quiet.

That's because an interview is a conversation under pressure. The skills that matter are saying your structure out loud, doing maths while someone watches and changing course when the interviewer throws in a new fact. You only get better at those by doing them, ideally many times, with honest feedback each time.

Why a human coach doesn't scale

A good coach is brilliant. They're also expensive and busy. One session is one mock interview booked around their diary. The best ones can cost over £400 an hour. Most people can afford a handful at most, which is nowhere near enough reps.

Practice partners are free but uneven. Your partner might not know what a strong answer sounds like, might go easy on you or might not be free the night before your final round.

What an AI interviewer does well

We didn't want a chatbot that says “great answer!” to everything. The interviewer in RoundReady is built to behave like the real thing:

  1. It follows the case. Each interview has a set path with data, exhibits and a right answer, so it can tell when you've gone off track.
  2. It pushes back. If your structure is vague or your maths is off, it asks the follow-up a real interviewer would.
  3. It scores you on what interviewers mark. Each part of the round gets a score and a note on what to fix.
  4. It's there whenever you are. At 2am the night before or ten minutes between lectures.
  5. You can fail as often as you like. Run the same interview again and see whether your score moves.
“Before you do the maths, tell me which number you'd want first and why.”

That's the kind of nudge that turns a recited answer into a good one. Hearing it once is useful. Hearing it twenty times until you do it without being asked is what changes the result on the day.

What it doesn't replace

An AI interviewer won't tell you which office has the best culture or put in a good word for you. If you can get a mock with someone who's sat on the other side of the table, take it. We see RoundReady as the reps you do around those moments, so that when you do get time with a real person you spend it on the hard parts instead of the basics.

Fair by design

The first interview in every track is free. After that it's a one-off pass for a week or a season, with no subscription to remember to cancel. Your transcripts stay private and there are no leaderboards. The point is to give anyone going for a top job the same amount of practice as the people who already know someone.

See what it feels like. Your first interview in each track is free.
