Create a great candidate experience

Candidates dislike whiteboard tasks - especially that senior developer who's been in the industry for 10+ years. Take-home coding assignments are flexible while being extremely candidate- and remote-friendly.

Our full stack assignments are designed to be quick so that your candidate won't be spending the whole weekend completing them. Create a hiring process that attracts top full stack talent, and hire the best talent in your industry.

How it works 

CodeSubmit setup is super easy. Create an account, choose from our library of full stack coding assignments or upload your own, and start inviting candidates.

Our review features make it easy to identify top performers and hire the best fit for your open roles.

Git Tree Review Flow

How CodeSubmit turns a repo into a review map

CodeSubmit does not jump from a Full Stack 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.

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

Map the tracked repo
The first pass builds a real file map so the review starts from the submitted project, not a stereotype about the stack.
Filter to reviewable files
Noise gets filtered out early so reviewers spend time on candidate-authored work instead of generated scaffolding.
Anchor to the root files
README and top-level manifests explain how the project is meant to work before deeper inspection begins.

That repo map turns into concrete review notes, likely test files, and live follow-up prompts for the hiring team.

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.
