I applied online. The process took 4 weeks. I interviewed at TNS Global (Gurgaon, Haryana) in Jul 2014
Interview
First test was taken. Simple test, not much difficult.
Then interview was taken. First general questions were asked and then 2 small cases were given just to check the thought process.
In the end some questions were asked related to statistics.
Was asked a lot about the competitor company information that I used to work in. Interviewer asked a bit unexpectedly more about that competitor company than my actual personal skills.

Just i was recommended by my line manager when i am interning. So i submit my resume which attached with my profile picture. There and the interview held one day with many interviewee in one stage.
