I applied through my university portal and got an on-campus interview invitation adter almost 3 weeks. The first round was with Senior Director and involved questions for Java and javascript debugging. It was more of optimizing the code rather than finding out errors, so was quite tough for me. I didn't think, I would get through, but I did get a call for super day and was amazed. The final round had 2 interviews, each with 1 of the developers for around 45 minutes each followed by small HR round (basic salary stuff and about the company details). The results usually took 1.5-2 weeks after every round. the process was smooth and professional.
