Through questions like this, interviewers are mostly trying to test your skillset (and its relevance to the role) as robustly as possible, so be prepared for multiple offshoots and followups. It could be a useful exercise to do mocks with friends or colleagues in Huawei to get a real sense of what the interview is actually like. Alternatively Prepfully has a ton of Huawei Research Engineer experts who provide mock interviews for a pretty reasonable amount. prepfully.com/practice-interviews Less

How would you profile the processor utilization of a process on an embedded system?
2 Answers↳
Answered that it could be done using procfs on an embedded linux system with kernel, but the interviewer said it was too high level and that I didn't have an OS which was odd since he said process. I then said a bare-metal program could use systick (or architecture specific implementation) or hardware timers to track WCET timing, still seemed to be an incorrect answer. I thought he might want a software approach and mentioned a few static profiling tools and schedulability calculations, but he didn't want that either. I eventually said you could mask interrupts, assert GPIO and track clock pulses but he didn't seem happy. I've thought this one over a lot but I'm not really sure what he was looking for... Less

Possibly looking for a hardware solution for a timer / interrupt based process. We've used LEDs turned on/off by software during certain activities. Hook that up to a signal analyzer and you've got a detailed view of the timing. Less
