The process took 2 days. I interviewed at Persistent Systems
Interview
First phase included an aptitude test consisting of quantitative, logical, technical questions, coding question and an essay
After clearing the aptitude test there were two technical rounds and one HR round.
I applied through a staffing agency. The process took 1+ week. I interviewed at Persistent Systems (Pune) in Feb 2009
Interview
The hiring process was very good...I had complete clarity on what was going on. the technical rounds were also in depth & challenging. The client round also was sufficient to understand their offerings, but you have to haggle a lot in the HR round for your salary structure.
Overall a good experience, but do not sell yourself short here.
