What it is
A platform for anonymous technical mock interviews with working engineers, alongside a public library of recorded interviews and a research blog that publishes data from those sessions.
The underrated part
The free recordings. Almost every candidate builds their mental model of a good interview from imagination, and the imagined version is far more polished than the real one. Watching a recorded hire and a recorded no-hire back to back recalibrates expectations faster than any amount of reading.
On the paid mocks
They are valuable at a specific moment, which is after the pattern work is done and before the real loop begins. Booking them earlier mostly buys you the discovery that you are not ready yet.
Best for: the two to three weeks immediately before real interviews.

Stuck on something specific?
Writing only gets you so far. If you want an answer to your situation rather than the general case, book a session and we will work through it together. Every session is free; a few slots open each week.
