I had got call letter from fresherworld. There were Three Rounds.All were to conducted in World Trade Center, Bangalore.On 10th June there was 1st round which was Written one,40 questions and 30 min was time.Questions were in 2 sections viz. English and Aptitude + Reasoning.You have to be quick and Accurate.Later on 12th I had got a mail regarding 2nd round.On 13th there was second round which was Interview.My No. was 40+(if I correctly remember).After two and Half hour they call my name.The Interviwer was Young one.It was more than an hour Interview.First he started with my resume,asked questions regarding Project then Hobbies and then Aptitude and then he asked a lot of questions regarding Puzzles and Real case base secenerio.I answer them with sufficient and the best possible ways. During these I had realised that they have already made their minds and trying to convince me why I am not selected for further round by asking Tough UPSE level Interview questions. Since I had asked some of those who were Interviewed earlier,These type of questions was not asked to them and also they said them to wait outside. Later I found that Those who were selected for next round which was HR was conducted on same day later.
