Total of four rounds. 2 technical+1 managerial+1 HR. Both technical and managerial round was good and mostly asked questions from core Java and Diameter. Interviewer were polite and friendly. The worst part was HR round. In my 4 years of professional career I have never encountered like him. Firstly I was informed a day before F2F round so I didn't update my resume, I informed abd it and expected package to the HR who scheduled my interview, she told me no issue with old resume and with the package. But at the company the HR was different and he was so rude. He was negotiating the salary like fish market and even I was talking to him politely he was yelling me and kept saying don't argue with me. I was literally stunned to see such people who handles the employee.
