I applied through university. The process took 2 weeks. I interviewed at Ecolab (Saint Paul, MN) in Nov 2013
Interview
I attended one day career interview event and got interviewed with three different people during that day. They were all from different finance functions from the company. Each interview lasted for about 30-40 minutes and most of the questions were generic questions, not many tough ones. The second of the day, they took you to a R&D center and showed you the history of the company. No written test was required for the interview.
