Frequently Asked Questions

How does the similarity detection work?

CodeGuard parses submissions into Abstract Syntax Trees (ASTs) to compare code structure independent of variable names or formatting. It also generates vector embeddings stored in a vector database to catch semantic similarities, even when code is heavily refactored.

What languages are supported?

CodeGuard supports the most common interview languages: Python, JavaScript, TypeScript, Java, C++, and Go. Additional languages are added regularly based on customer demand.

Can I adjust the sensitivity of detection?

Yes. You can configure similarity thresholds per role or per interview round. Set stricter thresholds for senior roles and more lenient ones for junior positions where common patterns are expected.
