2x more likely to pass
An analysis of about 100,000 technical interviews found engineers were nearly twice as likely to pass after about five mock interviews. Same people scoring better. They just practiced more.

Pick your interview type.
Not a chat window with a prompt. Each format gets the actual environment you'll face, with the interviewer talking to you the whole way through.
Coding
Real editor, syntax highlighting, live execution in Python, Java, C++, JS, and C#. Talk through it while you type.
System design
Whiteboard canvas, you sketch, the interviewer challenges your trade-offs out loud. "Why a queue there?"
Behavioral
Structured STAR discussion with follow-ups that dig, the same "tell me more about that decision" you'll actually get.
Then it tells you the truth.
Every session ends with a scored evaluation: communication, problem-solving, code quality, language proficiency, a hire verdict, and the specific thing to fix before the next one. Compared against your last session, so you can watch yourself get better. Scoring dimensions match the interview type.
What people say
“The follow up questions were simply amazing. Overall an ultra realistic interview experience, thank you.”
Mohan M · Prepping for Amazon
“The end-of-interview summary stands out a lot. The summary it gives me for what I say or don't say plus the comments on my implementation is invaluable. I've done a ton of interviews and a ton of Leetcode and I've never had that sort of summary before. It also helps a lot that it compares my current performance with my previous performance... it makes mock interviews so much more accessible than before.”
Aeron C · Junior SWE
“As someone who makes a living from coaching people to get SWE jobs at FAANG I was impressed by how the AI handled the interview at various points like first asking me for my thoughts and about my approach before "letting" me start writing the code... I feel like I'll be out of a job soon :)”
Alex V · SWE Interview Coach
“This tool is pretty great for someone like me. I have always been intimidated by tech interviews. Even the thought of a failed mock interview and the embarrassment I would feel after giving them had me avoiding them. This tool has helped me realise that I do suck, but I could be a lot worse, I am progressing and feeling more confident as time goes on, and that talking through my process is just as important as the solution, if not more.”
Sirat B · Prepping for NVIDIA
“I can 100% see this being a staple in every software engineer's interview prep process.”
Baid B · Apple Senior SWE
“The AI was extremely aware of the question I was working on and attentive to knowing I should not be using extra space for the question.”
Ben H · SWE Team Lead
“It was like a real one, the questions, the tone everything.”
