Codility tests 2015 engineering.JIA tests how engineers work now.
Codility's blank editor was designed before GitHub Copilot existed. JIA is built for the engineering reality of 2026.
Codility was built for a world without AI.
That world ended in 2022. The assessments Codility runs haven't changed to reflect it.
Banning AI in interviews filters out your best candidates.
The engineers who know how to use AI effectively are the ones you want to hire. A test that penalises AI usage systematically selects against the most capable people in the market right now.
A score with no context is not a hiring signal.
Codility returns a number. JIA returns a reasoning breakdown, a code quality score, an AI prompt log, and a structured voice interview transcript. One of these tells you whether to hire. The other doesn't.
A point tool creates more coordination work, not less.
Codility is one layer in a six-tool hiring process. You still need Calendly, Google Forms, an ATS, a screening tool, and a way to manage results across all of them. JIA replaces the whole stack.
What the candidate experiences. What you get back.

Codility solves one-seventh of the problem.
An assessment tool is stage 4 of a 7-stage hiring process. The six stages around it still run on spreadsheets, calendar links, and copy-pasted scores. JIA covers all seven.
Switch to JIA if any of these sound familiar.
JIA works best when the problem is bigger than one bad tool. If even one of these describes your hiring process, the $1.00 trial is worth it.
Start $1.00 trialYour best candidates declined your Codility test because they don't interview without their usual tools.
You've run three rounds of Codility tests only to discover the candidate can't explain their own solution.
You're paying for Codility plus Calendly plus Google Forms plus an ATS and they still don't talk to each other.
Your team uses Copilot daily but your hiring test penalises candidates who do the same.
A candidate scored 92% on Codility then failed to ship anything meaningful in their first quarter.
Your recruiters spend more time formatting Codility results into the ATS than evaluating candidates.
