Received an email from Alcon asking me to schedule an interview time with them through my college's jobsite. It was an on-campus interview. I spoke to 2 people separately. I first spoke with an engineer who asked me mostly about points on my resume. He asked what I was most and least confident and comfortable with. Next I spoke to someone from HR, who asked me personality questions: weaknesses, what I am proud of, why I want to work at Alcon, etc.
I thought things went well, but there were plenty of candidates and I did not get an internship with them.
