Mock Interview
Solving a problem and surviving an interview are two different skills. One you can do at your own pace with three tabs open. The other happens once, with someone watching, and you have to talk while you think.
We're building the second one. It isn't ready yet.
A clock that matters
Forty-five minutes, one problem, no pausing. The pressure is the point — reading a solution calmly at midnight is not the skill being tested.
Made to think out loud
Prompts nudge you to say your approach before you type it, the way an interviewer would. Silence is the most common way a good candidate loses a round.
A verdict, not a score
Where you stalled, what you missed, which pattern would have gotten you there sooner — written the way feedback after a real round should be.
Until then
The fastest way to be ready for a timed round is to stop meeting each problem for the first time. Work through the patterns, then the company sets — by the time the clock matters, the shape of the question should already be familiar.
