I applied through college or university. I interviewed at Alcon (Houston, TX)
Interview
First round is through phone--talked to a few engineers, mostly behavioral questions (describe a situation where a teammate was not performing adequately, etc...)
Second round was in person interview, talked to 4 different people. Questions were more technical and it took about 4 hours.
Interview questions [1]
Question 1
What is the last thing that you fixed? How did you fix it?
