Find out which topic you are worst at.
Ten minutes, out loud, on questions built from the posting. Then a score attached to a topic you can go and practise.
Free to start. You can stop partway and continue later.
- Kept across sessions
- Every answer, scoredNot a transcript you close and lose. The seventh attempt is comparable with the first.
- Named, not averaged
- Strongest and weakestReported as a topic you can go and practise, rather than as a single number.
- Built from the posting
- Its own rubric per roleA founding engineer round is scored against what that role actually asks for.
The posting becomes the questions.
Paste a job description and the round is built from it: the stack it names, the level it is hiring at, the kind of ownership it describes. A founding engineer interview does not arrive as generic behavioural prompts.
You answer out loud, which is the part you cannot rehearse alone.
The interviewer speaks, you reply, and the transcript builds beside you in real time. The gap between what you meant and what you actually said stops being invisible, which is most of the value in ten minutes.
“Today we will run through a quick ten-minute conversation covering your technical experience with TypeScript backends and your approach to owning systems end-to-end as a founding engineer.”
The score is uneven on purpose.
Rated section by section against a rubric built for that role, and kept between sessions so the second attempt at system design can be compared with the first. It is reported as a topic rather than averaged into a single number, because the number is not the thing you can act on.
Before your first session
What it asks, what it scores, and what it keeps.
You answer out loud rather than by typing, the questions are built from the posting you paste, and the result is scored against a rubric and kept. The record is the part a chat window cannot give you.
About ten minutes, which is short enough to do before a real interview. You can stop partway and continue later.
Your answers, section by section, against a rubric built for that role. It is reported as a strongest and a weakest topic rather than averaged into a single number, because the useful output is knowing what to go and practise.
No. You can pick a role and a level instead. Pasting a posting makes the questions specific to that job, which is worth doing when you have a real interview coming.
The transcript is kept so you can reread what you actually said and compare later sessions against it. You can delete a session at any time.
Be bad at it here instead.
Free to start, and the first session is usually the one that tells you the most.
