Same as others. 1st round a brain teaser, one programming question on pointers (debugging) and one embedded system design question with LED circuit. Not sure what exactly are they looking for.

Applied, interviewed and got invited for a follow up interview. Sent some dates and the following day was told the position closed. First interview as technical and included a pointer question, how to control an LED with a microcontroller (show hardware diagram and write a software driver with C), determine what a code snippet would print(pointers, references, and the three lightlbulbs riddle.
