I applied through university. The process took 1 day. I interviewed at ATA Engineering (San Diego, CA)
Interview
It's a full day of interviewing with multiple people throughout the company. You may have to give a presentation based on previous work or research. They just want to understand you more, describe the company to you, and see if you would be a good fit. There may be some light questioning on how you would think through a problem too, but it's by no means a drill session.
Interview questions [1]
Question 1
They sat around a conference table and just asked me to describe my life up to that point
