I applied through university. The process took 3 weeks. I interviewed at Caterpillar (Peoria, IL) in Oct 2015
Interview
Use the STAR methodology (Situation, task, action, result)
They won't even ask why you chose your major, why you deserve this internship. It's just all behavior questions, so just explain the situation that you were in, what were you tasked with, the action that you took, and what was the result.
Don't mention "we," mention "I" during the interview
Interview questions [1]
