Question 1

What is CodeArena?

CodeArena is a B2B technical interview suite for companies hiring engineers in the AI era. It measures how candidates code, direct AI, critique generated output, and verify whether AI-produced code is correct.

Question 2

How is CodeArena different from traditional coding screens?

Traditional coding screens often assume candidates work without AI. CodeArena is built around the modern workflow: candidates solve coding tasks, write prompts, critique AI-generated work, and verify outputs with evidence.

Question 3

Does CodeArena have a free company tier?

No. CodeArena company assessment workflows are paid. Starter is the smallest paid plan for one real hiring loop, and companies pay for candidate invite links, automated grading, reports, and hiring workflows.

Accepted Answer

CodeArena supports 14 programming languages: Python, JavaScript, TypeScript, Java, C, C++, C#, Go, Rust, Ruby, PHP, Kotlin, Swift, and SQL across practice and company assessment workflows.

What does CodeArena Discernment evidence show?

Accepted Answer

Discernment evidence summarizes available seeded-defect judgment: whether a candidate catches real problems, avoids false alarms, and expresses uncertainty where the interaction captures it. It is one reviewable input, not a final hiring verdict.

Question 6

Can I practice coding alone on CodeArena?

Accepted Answer

Yes. Developers can use public practice surfaces for coding problems, SQL, language fluency, and prompt challenges. Company interviews are paid by hiring teams.

No. Companies pay for interviews. Candidates join through invite links and can use public practice resources to prepare.
