Technical interview for a System Software Test & Development / SDET Student position. The interview included one coding question about string compression, including a short follow-up about doing it in-place with constant extra space. The second part was a system testing question based on a simple hardware diagram with two systems, a MUX, and Flash memory. I was asked how I would test the system using the given APIs. There was also a short discussion about locks and shared hardware resources. Overall, the interview was practical and focused on coding, testing approach, and clear explanation.
