CMC Associate IT Engineer interview questions

Well It started with one common written test for Aptitude and Technical knowledge. Both had cutoff marks, so I had to clear both cutoffs. Then there was a technical interview. In that they asked basic questions from Engineering curriculum. After that, there was an HR round, there interviewer asked questions related to you and some easy puzzles. And then there was a Speed and Accuracy test, where they tested your skills like accuracy, speed, data manipulation and interpretation, observation and pressure handling.

test and tech and hr interview.. they shortlisted candidate based on their score on co-cubes. therefore no apti test was there for us. hr interview was easy but in technical he asked too many questions and they will try to confuse you by asking are you sure.. is this correct
