Had the first interview after an engineering career fair, was mostly company knowledge questions (why you want to work for boston, why this position, etc.). Was referred to a recruiter in the location I wanted and kept in contact but then they slowly stopped responding regarding that position.
I applied in-person. The process took 4 weeks. I interviewed at Ecolab (Chennai) in July 2018
Interview
I had a 3 round telephonic interview after I had a walk in interview. Which tested on some basic chemistry questions and post clearing that I was sent to a group discussion. After being selected in GD had a personal interview all in one day and told me I would be called. The next week I had a call with regional sales manager and post that with national sales manager. I didn't clear this round as they felt I was overqualified or not correct for the position.

I applied through a recruiter. The process took 1+ week. I interviewed at Ecolab (Hastings, NE) in Feb 2018
Interview
I had to drive an hour to meet the hiring manager in a hotel lobby which was loud and full of people. The face to face interview was a waste of time considering everything could have been discussed on a phone call.
