Embedded Systems Engineer interviews — common questions

Who is this Embedded Systems Engineer interview plan for?
It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Problem-solving Test round for a Embedded Systems Engineer role. It gives you a 60 min script to follow in the conversation — 4 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.
What does the Problem-solving Test round assess?
This round is focused on: Problem Solving, System Design, Analytical Thinking, Diagnostic Skills, Troubleshooting. It works through Introduction, Problem-Solving Challenge and Closing, scoring against 28 observable signals, with follow-up prompts on all 4 questions for going deeper where an answer is thin.
How is the 60 min split up?
Introduction (5 min), Problem-Solving Challenge (50 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.
