Identify Top Tornado Developers

Evaluate Tornado skills

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

Identify top performers and rest easy knowing that your new Tornado 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 developer talent by providing an excellent candidate experience. Build your employer brand and hire the best talent in your industry.

How it works

Getting started is easy! Simply create an account, choose from our library of 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 Tornado 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.

Map the tracked repo

We start from the full submitted tree so the review begins with actual structure, not guesswork.

Filter to reviewable files

Generated and vendor noise gets stripped out before anyone mistakes framework clutter for candidate work.

Anchor to the root files

README, requirements, and manifests show how the service is meant to run before deeper claims are made.

Carry it into follow-up

Top-modified files, likely tests, and risk hotspots become the map for live CodePair discussion.
