Abalta Technologies interview questions

1st round 20 online C++ question that just drill deep into the C++ keywords itself, not real logical challenge, either you know it or don't, not really some commonly used functions either, pretty useless; 2nd round skype interview (1 to 1 face to face), the interviewer is very immature in the interview process, did ~10% talking with a lot of dead air, just kept drilling into one programming question for one whole hour, talked about nothing else, not even asking about relevant experience really.
