Cockroach Labs

Cockroach Labs documents its interview process end-to-end. After a 30-minute recruiter screen, candidates take a 30-to-60-minute technical phone interview on Google Hangouts with coderpad.io (some roles add a 1-to-2-hour take-home exercise); the virtual onsite is four to five exercise-based interviews run in a single block, after which an internal hiring committee independently approves each hire. A separate firm post on updating the engineering interview describes the format as deliberately practical — tasks that resemble day-one work rather than abstract algorithms. The exercise format means a typical LeetCode-only prep loop does not transfer cleanly here, so a candidate is preparing on two tracks if they are also interviewing at firms that test purely on algorithms.

Cockroach Labs runs an engineering internship program branded Intern & Evolve, with Winter, Summer, and Fall cohorts hiring backend software engineering interns into the New York City office. An intern profile from the SQL Foundations team describes the Winter cohort as roughly four months, with each intern matched to a single CockroachDB engineering team and owning a feature end-to-end (design doc through shipped code) rather than completing a curated curriculum. The footprint is small and US-based, so for a student weighing distributed-systems exposure against breadth of intern peers, this is a depth-on-one-team bet rather than a large-cohort one.

Cockroach Labs publishes its full interview process and engineering exercises on GitHub as an open-source repository, and explains the reasoning on its own engineering blog — an unusually transparent stance for a venture-stage employer. The internship sits inside a single New York office and is engineering-only, with no rotational tracks: interns work on the distributed SQL database product alongside the engineers building it. The published exercises mean a candidate can calibrate prep against the real format before committing an application slot, narrowing the usual uncertainty of an unfamiliar interview loop.
