The process took 2 days. I interviewed at Larsen & Toubro (Hazira) in Mar 2008
Interview
Initially there was a skills test that included math, verbal and general reasoning. It was quite straight forward. I was selected and was informed about the on campus interview that took place after a few days. It was one on one and the interviewer was really friendly. He started with a few technical questions and then drifted to HR. It lasted for more than 45 mins but to be honest, didn't seem like that long. I got the confirmation after about a week.
I applied through college or university. The process took 1 day. I interviewed at Larsen & Toubro in Jan 2007
Interview
Selection process is very fare. It consists of aptitude test followed by presentation on project what you furnished in college and interview together. People in the interview panel were very cooperative.
