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.
