The questions themselves deserve a separate paragraph. The interview was split to several quizzes: hardware design, rtos-related, c, c++, linux, security. Majority of the questions was single-answer test questions. Few open questions to write some snippet. The hardware and security part was quite ok. The rest was not. The C/C++ questions were based on a code snippets prepared exactly for interview purpose. So, there were some crazy-looking constructs like 3[arr] + (arr+1)[1], !!!arr, &(*(&arr[1]+1)+2). Things that you should never see on production. I don't see a point of asking such questions. This kind of questions doesn't check if you're good engineer or not. There were no good coding practices questions, no software design-related. All C++ questions were pre-C++11.
Interview is technical, there were around 10 to 20 questions. About C Programming, software design, development, unit testing, functional testing, verification and validation. Software Integration, qualification testing. Micro controllers, Testing tools etc..
