The written , 2 technical and 1 managerial round was good and very professional. I did not do well in the managerial round.This took a whole Saturday.The HRs and interviewers were very professional and arranged things well. F2F rounds were bit challenging. But, after 2 days got a call from another HR saying, another team member wants to discuss with you and i have to come to the office the next day and the interview was scheduled and in the mail i received from HR , it was mentioned as job position:Technical architect , after i called the HR for confirmation on the position , he said i just sent the call letter and forgot to delete content of mail. I went for interview the next day, two guys came to take the interview, both of them behaved like they want to take some revenge on me and were behaving like a critics for every answer i give. they were giggling, yawning(they just had come from lunch, did not even wipe their hands). Very very unprofessional attitude by the last interviewers.
