I interviewed for a role of C++ developer in Zurich. First round with HR went well, very responsive and helpful lady. Second round, the techical one, was a nightmare of every developer out there. For some reason post-USSR C++ programmers think that it is necessary for every developer to know C++ internals inside out to be able to write programs in it. But I was not applying for a position of C++ compiler developer nor for a C++ standard committee member. Questions about vtable, backing implementation of a deque or a very smart (deliberately obfuscated) "what happens if birds could swim" questions are meant to confuse and to fail a candidate, not to assess a candidate's ability to write programs in C++. 1.5 hours of grilling on every imaginable detail of C++ internals and tricky and confusing "what will this print?". And OF COURSE classic ghosting in the end.

Only positive impression It's about 1.5 hours interview with practical experience accentuation Mostly about code reading and writing + some English level checking for non-natives You can easy pass it with middle/middle+ C++ level
