Assessment

Repo-based take-home challenges

Give candidates a take home project worth reviewing: a real repo, a familiar workflow, and code your team can discuss with confidence. Automated AI review surfaces repo structure, testing gaps, and follow-up ideas so reviewers can focus on signal.

Assignments matched to your stack, role, and hiring bar

Candidates use their own tools and submit reviewable Git changes

Automated AI review flags repo structure, testing gaps, and follow-up ideas

Open the same codebase in CodePair for follow-up

CodePair

Live coding interviews in a shared codebase

Beyond vibe coding, CodePair gives you a shared IDE, terminal, and repo so you can see how candidates read code, debug problems, collaborate, and use AI with judgment in real time.

Work together in a real codebase with multi-cursor editing and full project context

Build, run, and debug applications side by side with terminal access included

The AI agent is visible to both sides, so prompts and decisions are part of the interview

Take-Home Challenges

Repo-based take home challenges show how candidates scope, build, and submit code in their own environment. You get something worth reviewing, with clearer signal and less grading busywork.

Try Demo Challenge Learn more

: Work that matches the job: Candidates solve realistic product and engineering problems instead of memorized interview puzzles.
: Extensive challenge library: Start from proven assignments across major languages and frameworks, or upload one built around your stack.
: Candidate-first Git workflow: Candidates work on their own machines, with their own tools, and submit reviewable changes your team can actually discuss.
: Create or remix with AI: Start from a job post, a role brief, or an existing assignment and let AI draft the first version in a real repo.

Live interviews in the codebase that matters.

CodePair

CodePair turns any submission into a live collaborative session inside the original repo. Instead of whiteboard hypotheticals, your team can ask follow-ups grounded in shipped code and real tradeoffs.

Try CodePair Learn more

: Shared repo, real collaboration: Pair in the full codebase with multi-cursor editing and the same context on both sides.
: Visible AI usage: See when candidates reach for AI, what they ask, and how they validate the result.
: Builds, previews, and debugging in one place: Run the app, inspect output, and work through decisions live.
: Natural follow-up on submitted work: Start from the take-home or Bytes task they already completed so the conversation stays grounded in actual code.
