Written - Aptitude and English. English of quite high level but repeatition of previous papers. Aptitude - simple to medium difficulty level. It was followed by an easy going cellular technology basics based technical interview and then an HR interview. (I took it just after graduation). Ironically, no one in the company, except the core HR and of course those from good educational background, would communicate in even a simple fluent English.

It was 1 day long, not very hectic, started from 10am and ended at 6pm, at the end of the process they revealed who were selected so didnt have to wait long, written round was well organised as well as techincal and HR interview.
