Q3 Technologies SSE .NET interview questions

They called me for interview on 2nd july 2016. 1st round was an aptitude test. Why these guys are having aptitude for an experienced guy. After 1st round HR told me to come on Monday for interview as our all managers leaved for the day. This should not be an answer if you called guys for interview. But that was OK for me. On Monday, I went for the interview round, I met the HR and she was shocked while looking me. She asked me I didn't told you for interview, I told you to call on Monday, it was a shocking news for me. After that she told me to sit outside. After 1 hour a manager came, and he was asking the questions from the topics that was not mentioned in my resume. He asked me a question for exception handling and I answered that question correctly, but manager told me this is wrong. After coming home, I searched that question on Google and answer was the same as I told him. I totally unsatisfied with the interviewer.
