Firmware Engineer Interview Questions

2,134 firmware engineer interview questions shared by candidates

Apparently there were some questions that I answered incorrectly or inappropriately, but I never got the opportunity to find out which these were. I thought I did pretty well with the onsite interviews actually, and walked out feeling pretty confident. So it was a surprise that they chose not to make an offer. Technical questions included issues about program structure (main loop code versus ISR code), concurrency issues with respect to interrupted operations (crtitical sections and mutexes), timers, i2c, SPI and other interfaces, etc.

One question I do remember, because I should have known the answer, was how do you detect a stack overflow - ie the pointer wrote past the top of the stack. You handle it the same way you would if you created your own controlled memory heap.
