Same questions here. This other day I was interviewing with a recruiter for a Go dev position, then she asked "what is a map?", couldn't believe such a basic question was being asked, proceeded to explain, then asked her why such a basic question; she said most applicants couldn't tell her what a map was (shock face). Next question was "what is a hash table?", even more shock... I'm a Computer Engineer who started to program when I was 12 in a 286.
