This is an automated process, which was a surprise. It was very easy and what they ask you to do is clear and easy to follow. Each email contains instructions. Be camera ready always.

Applied via their website, was emailed by a recruiter a couple days later for a phone interview, mostly behavioral and asking about my resume. A few days later I heard back from the recruiter and set up a second interview. Second interview was very similar to the first, asking about work I've done and how it's applicable to this position. Few days later I got the offer for the internship.
