Why candidates use this
The coding rounds put you under the same time pressure as a real technical interview. Write a working program from a brief within the time limit — exactly what employers test.
Interview-style questions on fundamentals, analogue I/O, PID, safety, and communication protocols. Your answers are scored against model answers with explanations.
Complete a track above the pass threshold and earn a certificate with a unique verification URL. Share it in your portfolio or LinkedIn profile.
