Real interview situations with four ways to respond. Pick one, then read why it wins or why the others lose the room. No timer, no lives. A plain count at the end and a list of what to reread.
The technical and behavioural sets draw ten scenarios from all the tracks, in a new order each time. Company tracks are a style of question, not a claim about that company's process.
Read the situation as if it were your interview. Say your answer in your head before you look at the options; the options are there to check your instinct, not replace it.
Every scenario is made up. The numbers inside it (requests per second, users, percentages) describe that situation, not the world. The "stronger" answer is the one an experienced interviewer would want to hear, and the explanation says why. If you disagree with one, that is worth a conversation with a senior colleague.
Nothing is stored or sent anywhere. Reload the page and the count starts again.
ClapAssist runs on your Mac or Windows laptop during the video call. It hears the question and shows short spoken-ready prompts. The app stays out of screen share on every plan; only you can see it.
