Aon IT Trainee interview questions

They had initially an aptitude test conducted in our college which I cleared. Then we were called to their office where they held a group discussion process and I went through that too. Further more they had a very wierd and long brain freezing test called GATE test which really was a lot of questions about management and behaviour environment in an office . The technical interview was not bad. They did ask a few tough questions related to new technologies like automation testing and etc. The last round was HR which went smooth.
