I applied through university. The process took 1 week. I interviewed at Impulse (India) (Gurgaon, Haryana) in May 2013
Interview
1st round- personal interview
2nd round- design project
3rd round- final telephonic/PI
The interviewers were very chilled out and logical. Questions asked were very relevant and to-the-point. They were very flexible in terms of the interview schedule which showed how much they value other's time and priorities.
