Three round were there all together for this off-campus round in Pune campus.
No of candidates were around 2.5k in 6 different batches.
1st day only aptitude was conducted, Aptitude : not tough, but it was like a rapid fire, where the passing percentage was 70% because of which half of the chunk got eliminated in the first round itself.
2nd Day : Group Discussion in the groups of 10. here also half of the crowd got eliminated. They hardly took 2-3 candidates from each group.
It was then followed by the Technical Round:(I was an ELEX candidate)
Questions around ur branch, final year project, logical puzzling, situation based questions, case studies. (for IT/COMPs it was full of JAVA, C, C++, .Net etc.) Again as similar with previous rounds, 2/3 of the crowd they eliminated in technical.
HR Round : Mine was pretty good. HR was damn chilled, made me comfortable nad asked the questions around my resume, hobbies, asked about the shift, relocation and all. Overall nice.
