I was selected from a pool campus held in Acropolis Institute in Indore on 9th March 2014. There were 4 rounds. First round was combination of Aptitude and verbal. There were around 170 questions, which need to be answered in 80 mins. You just need to manage time between the sections, not that difficult phase.
The shortlisted students were called for technical interview, I am from Computer Science, so they asked a few questions about my project, and some basic concepts about OS. After that there was an extempore round, which was unexpected for me, but I gave my best. They gave an on-spot topic to speak. You need not to worry, just speak what you mind says at that time, but in good English. The final round was the HR Round, in that they asked a few questions about my career goal and what if I was not selected. The result took a good amount of time, but finally I was selected. Hope this helps you to prepare well in your attempt.
