Your question is Owning an Ambiguous Embedded Failure. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you were given a vague or incomplete problem in an embedded system and had to take ownership to drive it to resolution. Walk me through how you prioritized what to investigate, how you communicated progress, and what outcome you achieved.
