What programming languages can backend candidates use?

We support TypeScript, Python, JavaScript, Go, Rust, Java, C, C++, PHP, Ruby, and Bash with real-time code execution.

Can I test database and SQL skills?

Candidates can write and discuss database queries, schema designs, and data modeling using the code editor and whiteboard.

How do I evaluate system design for backend roles?

Our collaborative whiteboard lets you and the candidate draw architecture diagrams, discuss tradeoffs, and walk through distributed system designs.

Does the code actually execute or is it just an editor?

Code runs on real servers with actual output. Candidates can test their solutions, debug errors, and iterate — just like real development.

Can I create custom backend coding challenges?

Yes. Create your own challenges or use our pre-built question library. You can define inputs, expected outputs, and evaluation criteria.
