Identify Top FastAPI Developers

Evaluate FastAPI skills

If FastAPI is part of your stack, then you'll probably want to see how your candidates work in FastAPI, not just Python. Discover how your backend developer candidates complete FastAPI coding tasks and rank them based on skill.

Identify top performers and rest easy knowing that your new FastAPI hire can get the job done.

Create a great candidate experience

Hiring managers know that candidates dislike whiteboard tasks. Take-home coding assignments are a great alternative, because they’re flexible, candidate-friendly, and completed asynchronously.

Create a hiring process that attracts top FastAPI talent by providing an excellent candidate experience. Build your employer brand and hire the best talent in your industry.

How it works 

CodeSubmit makes it easy to create, assign, track, and assess FastAPI take-home coding challenges. Create an account, choose from our library of carefully crafted FastAPI coding assignments or upload your own, and start inviting candidates.

Our suite of review features makes it easy to identify top performers.

Git Tree Review Flow

How CodeSubmit turns a repo into a review map

CodeSubmit does not jump from a FastAPI 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.
