I applied through college or university. The process took 2 days. I interviewed at Persistent Systems (Nāgpur, Maharashtra) in Sep 2012
Interview
First there was an aptitude test. It consisted of basic components like verbal, quants and reasoning but there were also around 10-15 questions of software testing which non-CS/IT students might find difficult. After the aptitude test, there was 1 coding round in which CS/IT students had to right the whole code and Non CS/IT students had to just write the logic. There were a total of 2 technical interviews and 1 HR interview.
