They call me for the C++ round and start asking C questions. This was 2nd round and I have never expected such a useless and funniest interview of my life. The interviewer doesn't even know how to allocate memory to a pointer :P . He started an argument but when he realises the solution build is successful without error he got shocked. Later I came to know that guy is having 20 yrs of experience. and I am like OMG god save crestron .
