Litmus

Litmus is a technical hiring platform that generates asynchronous coding assessments from a company's own context, such as its repositories, tickets and job descriptions. Rather than generic puzzles, candidates work on realistic tasks scoped to a specific team, in an environment that resembles how that team builds software. The platform generates the assessment and a grader, and benchmarks an AI agent baseline run against it. Candidates install a command line tool, initialize a task, work in their own editor, and submit with a tracking log. Litmus records how someone builds over a real task, how they use AI coding tools, and how they explain their decisions, and presents that as hiring signal. Candidates can sync with an applicant tracking system, or the whole process can run inside Litmus. It is aimed at engineering teams and startups that want to reduce the engineering hours spent writing interview problems, running screening calls and grading take home tests. The founders say they worked at Meta, Two Sigma and Morgan Stanley before starting the company. Pricing is not clearly published on the live pages, and the site offers demo booking.
