Recruiter organized two phone calls with them. First interviewer was a nice person and got through to the next stage. After the second phone screen I got rejected. The whole process was quick, couple of days between the two calls.

I would like to point out the second interviewer arrogant style and unconstructive/negative feedback after the interview which made me feel quite humiliated. I interviewed at many places before but I have never come across such an arrogant and inflexible attitude.

I would advise them the next time to send only a succinct "unfortunately we are not going to proceed forward." message instead of the belittling one which I received.

Overall the place left quite a bad impression on me and this interviewing style is not good for the company's image at all.

Lots of random implementation details about various c++ standard library classes are presented in an interrogative style. You either know these right away or you do not.
