I recently wound up at Apple and I just wanted to shoot you a note of thanks for helping me get there! I probably mock interviewed around 6 or 7 times, and not only had a great experience, but met some interesting people along the way.

I've been using the past couple weeks... I interviewed with Amazon and Lyft last week and have gotten offers for both. I'm absolutely certain without the practice on here I would have flopped, but now doing a coding question almost feels like home (almost 😄 ).

Practice & get feedback

Practice anonymously with engineers who have worked at Google, Facebook, Twitter, Amazon Web Services, Microsoft, and more. Your interviewer will not know who you are or anything about you.

Get fast-tracked at companies

Do well in practice, and get invites to interview anonymously with great companies. That means you can skip right to the technical screen without talking to recruiters, touching your resume, or haranguing your friends for referrals.

Unmask & get the job

At the end of each technical screen, if things go well, you can unmask. The next step is almost always an onsite.
