zCon Solutions Senior Software Developer interview questions

Interview process was good , 1st was technical round, 2nd was managerial round, I have cleared the technical round , but managerial round was worst as he was asking some random questions and he want answer as per his thinking, also he was not professional during interview. My suggestion is that if you don't want to select any candidate then don't treat them bad , it is ok to not select. worst experience ever.
