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.

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.
