Cla64.ai

Cla64.ai helps developers prepare for technical hiring with realistic coding interview practice. Key features: • Timed exercises built on real codebases • Cloud-hosted workspace with no local setup • Built-in assistant that helps like a teammate when you get stuck • Interviewer-style follow-up questions that ask why you chose each approach • Bug fixing and test-writing challenges • Support for Python, JavaScript, TypeScript, Java, and C++ • Recorded practice sessions you can review afterward. Each exercise drops you into a realistic scenario, such as tracing a bug in a sale log, reproducing it with a test, and shipping a fix. The work happens in a browser-based workspace, so you can start immediately on any device without installing a development environment. The assistant offers hints and explains code when you need a nudge, while the interviewer persona pushes you to justify your decisions the way a hiring manager would. Practice builds the skills that matter most in live interviews: reading unfamiliar code, explaining your reasoning out loud, and writing tests that prove a fix works. Sessions run about 15 to 60 minutes, so they fit around a busy schedule, and a free tier lets you try the experience before committing. Designed for software engineers preparing for job interviews, bootcamp graduates, students aiming for their first developer role, and experienced engineers returning to the job market. Coding clubs and instructors can also use the challenges to run mock interview sessions.
