Practice code review, debugging, API design, SQL, security auditing, Git workflows, and more. Real-world scenarios with detailed AI evaluation.
Interview prep platforms focus on algorithms, but day-to-day engineering requires a much broader skill set. ByteMentor AI's engineering skills labs cover what you actually do at work: review code, debug production issues, design APIs, write SQL, audit security, manage Git workflows, and make architecture decisions.
Code Review — find bugs and anti-patterns in realistic PRs. Debugging — locate and fix bugs with progressive hints. API Design — design REST APIs evaluated on conventions. SQL & Database — write queries and design schemas. Pair Programming — turn-based coding with AI. Git Challenges — merge conflicts, rebasing, real-world scenarios. Architecture Decisions — write and analyze ADRs. Performance — identify N+1 queries, memory leaks, unnecessary re-renders. Security Audit — find XSS, SQL injection, auth bypasses.
Each lab generates unique, realistic scenarios — not textbook exercises. The code review lab shows you actual pull requests with subtle bugs. The debugging lab gives you production code with real error symptoms. The security lab presents you with code that has OWASP Top 10 vulnerabilities to find. Every attempt is different.
