At first I was asked about my previous experience and projects I had worked on. How I made certain things work and why I picked particular solutions. The 2nd stage involved hardware (serial comms, registers etc) and coding questions. Some of the questions were: What is stack and what is heap What is code coverage What is unity checking What is version control Floating point to fixed point conversion Why would I not use stdlib in an embedded device What are stdlib’s drawbacks What are race conditions and how do I deal with them What is critical section and whether I have used it In the end I was interviewed by the technology director who gave me a puzzle to solve: In a given vector with N number of random integers, there is one duplicate. Find its position and which number was replaced.
