The most important question asked me to describe a challenging project I worked on, as it highlighted how I handle pressure, collaborate with others, and deliver results.
Asked about technical background, experience, etc. Some questions to evaluate professionalism, personality. Exactly what should be asked to determine potential for success in the position.
They ask for you to do a code review of some code snippets. In particular, they had a snippet with the malloc() family of functions which is really weird since using dynamic allocation on RTOS and embedded systems is frown upon. So this question was not relevant at all for the job since you'll never be using dynamic allocation in most embedded systems unless you want things to catch fire and explode. It's almost as if they didn't know what to ask for, but found that question online and though it would be suitable to use it on the interview.
They also ask if you recognize some C declarations as valid and ask you to comment on what they do, like a function pointer and a const volatile pointer variable.
- write a function to check if array is in sorted order
