ADP Sr. QA Engineer interview questions

Interview process was lengthy, time consuming, first round was not so difficult but interviewer did not know the answers of the question, my answers were correct still he was trying to prove me wrong. I got selected at first they were ok with 2 months notice period and then suddenly changed their decision that they need some one who can join immediately. HRs are unprofessional don't know how to talk when you call them.
