I applied through university. I interviewed at OSIsoft (Bethlehem, PA) in Apr 2015
Interview
It was very laid back. They asked mostly behavioral questions, and a couple simple logic puzzles. I was a chem E undergrad applying for the position so they didn't ask very technical computer questions. I was interviewed by two people, and there were no tricky questions. Everything was very standard-- what are your strengths/weaknesses, etc. They seemed a little desperate to hire engineers.

Question 1
If you have one large cookie, two small cookies, and a knife, how would you decide whether to choose the large cookie or the two small cookies in order to maximize your cookie consumption?
