Embedded C/C++ Engineer

Candidates typically undergo three rounds: a technical screen covering embedded C/C++ fundamentals and RTOS concepts, a second technical interview focusing on system design and debugging scenarios, followed by an HR interview assessing cultural fit and communication skills. The process is rigorous but fair, with interviewers often providing constructive feedback.

Round 1: Technical (Embedded C/C++ & RTOS) → Round 2: Technical (System Design & Debugging) → Round 3: HR
