How we hire
Apply with the form on oll4.com. A person reads every application. If your experience fits the role, we send you a practical challenge: a small codebase from a fictional company, with a few real problems to fix, one small feature to build, a pull request to review and a short note on your decisions. The clock starts only when you press Start. Use whatever AI assistant you use at work, and tell us how you used it. A person reads every submission, we invite strong ones to a 30-minute call about their choices, and every submitter gets our answer.
