Many sources. One person in front of every question.

Interviews we sit ourselves

We are a group of engineers who sit real loops and write up what was asked.

Public experiences

Threads and writeups from people who sat the loop, across several forums, read daily.

Community submissions

Experiences and single questions added by people who have just interviewed.

Placed in its loop

Every question says which company, round and level it came up in, how often, and when it was last asked — so you prepare for the loop you are about to sit.

Curator review

A person approves, edits or rejects every row.

Committed Contributor · waitlist open

A rejection you can cash in.

Give interviews. Share what you were asked. Committed Contributors earn 50% of the profit made from questions sourced from their interviews.

01Join the waitlist. Tell us your role and how often you interview. We reply to everyone, and we start small because the team is small.
02Share each loop. After an interview, submit the experience. We extract the questions from it; you confirm them before anything moves.
03A curator verifies and attributes. Every question is reviewed by a person, and we may ask you for a few details that show the interview happened — the sort of thing you already have. Published questions are credited to you on your profile, permanently.
04Profit is shared. Profit attributable to your questions is calculated per the published model. Half of it is yours, with a statement showing the working.

How the profit share works

Share your interview. Earn from it.

The full calculation model — how profit is attributed to a question, and how your share is computed — is published before anyone is paid.
