Centina Systems interview questions

Really disappointing with interview. First it was teliphonic then i went for F2F. In F2F they took two technical rounds and last round was with MD of this company. These three round on interview took two hours. They called me in week days. First round of interview taken by a guy which having may be 5-6 yers of experience. He took one hr interview and asked java question,problem solving and some of the telecom domain . I replied most of the answers .Then he sent me for second round. In second round two guys came. They ware be 10-15 yrs of experience. Both ask only java questions and current project. I given all of the answers. Most of my answers were correct. Finally i went to the third round with MD of this company. He read my resume carefully and marked so many lines and noted down my skills and domain knowledge on that resume. He asked my Current and expected salary. Then he asked leave for the day will let you know. Then they did not inform me for two days. Then i sent a mail to them ,then they replied SORRY YOU ARE NOT SELECTED FOR THE NEXT ROUND. Hahaha , I was surprised and thinking is there any more round was pending after MD round and salary discussion. I agree, those guys were more exp than me but as a four years exp of mine i can also understand how was my interview. Some time i also take interview , if you guys have caviler then you can easily judge any person withing 15-20 mints. Don't waste time of others to prove that you are smart. And finally got a mail of rejection after two days of wait.
