Average dev challenge
Accelerate challenge
AI tools have broken (most) developer assessments
We solved this problem before the AI hype.
Where coding assistants struggle, real devs thrive.
By creating an approach that identifies highly skilled developers.
What are the attributes of a highly-skilled developer?
They’ve mastered their tools and techniques, enabling them to deliver quality software quickly and reliably.

The Accelerate approach
Candidate-centric
Progressive requirements and time penalties
Objective Metrics
Candidate-centric
We respect candidates’ time and workflow:
- Complete the challenge on their own schedule. Pause and resume anytime.
- No live interviews or artificial pressure.
Candidates use their own tools:
- Any IDE, testing framework, or AI coding assistant.
- No lock-in to custom environments or obscure platforms.
Real-world development, not academic trivia:
- No need to memorize sorting algorithms or graph theory.
- No specialized domain knowledge require.
Progressive requirements
By using incremental rounds of changing requirements, candidates MUST evolve their code.
This reveals their true skills.
High-performing developers adapt quickly.
Penalties
Candidates receive time penalties if the code submitted does not match the requirements.
Good developers balance quality and speed.
Bad ones hack through and receive time penalties.
Objective metrics
Accelerate collects key metrics during the challenge and generates a detailed report.
Timings.
- Clock Time.
- Time penalties.
Code evolution.
- Test coverage.
- AI use.

What do our clients say about AI and our challenges?
"Our Accelerate challenge is immune from a one click solution.
If candidates use AI as a tool in writing code a little bit faster then that's actually a good sign for me.
I am looking for engineers who leverage new technology.
The Accelerate report flags where candidates have likely used AI.
We use this to check their understanding of what they've written in the technical interview."
Will Hayes, Co-Lead AI R&D at Invisible Technologies
What do candidates say about our challenges?
Candidate feedback given to our clients:
"It was an interesting challenge with plenty of edge cases! The time penalty aspect for incorrect answers was not something I had experienced before, but definitely simulated the "risk" of deploying to production.”
“The challenge was fun. I probably enjoyed it a bit too much. I thought it was a much nicer way of doing a coding challenge.”
“Thanks for the opportunity to participate in this challenge. I thoroughly enjoyed it. I must say that this way of testing is more relevant and different than other tests I’ve given before. It closely represented the day-to-day coding style…I hope to see more and more companies adopting this style of screening.”
