Evaluate for on-the-job skills

Leverage Gatsby coding assignments to understand how candidates work in real-life situations. Brain teasers won't show you how your candidates build apps, but our Gatsby challenges will.

Rest easy knowing that your next frontend dev is ready to hit the ground running in Gatsby.

Provide an excellent candidate experience

Our software works for companies of all sizes, and our goal is the same for all of them: to help them identify their next hire while providing the best candidate experience possible. Our challenges are designed with the candidate in mind.

Every assignment offers candidates the opportunity to shine. And unlike some of our competitors, our plagiarism detection features won't violate their privacy.

How it works

Create an account, choose from one of our Gatsby library assignments (or upload your own), and start inviting candidates! Candidates will complete tasks using their preferred development environment.

Your team stays up to date on candidate progress at every step so that you can hire quickly and with confidence!

Git Tree Review Flow

How CodeSubmit turns a repo into a review map

CodeSubmit does not jump from a Gatsby take-home straight to a thumbs-up or thumbs-down. The review flow starts by mapping the full git tree, then filtering obvious generated and vendor noise so reviewers get a fair file map before deeper review begins.

File listings alone do not decide anything. The tree is the map, then reviewers read the README, manifests, and top-modified files that explain how the submission works before they turn it into a candidate-friendly take-home review and a sharper CodePair follow-up.

Fair-review baseline

File listings are discovery, not evidence. Generated and vendor noise gets filtered so the review starts from candidate-authored work.

We enumerate the submitted tree first so reviewers see the real app shape before they interpret behavior.
Filter to reviewable files
Build output, vendor folders, and obvious noise get dropped so the review stays candidate-focused.
Anchor to the root files
README, package manifests, and config files show how the project is wired before anyone makes architecture claims.

Modified paths, likely tests, and review hotspots feed straight into a sharper CodePair conversation.

The result is a cleaner handoff for hiring teams: concrete paths to inspect, stronger AI summaries, and live follow-up topics that stay anchored to the repo.
