I got a phone interview by talking to a recruiter at my schools career fair. It was 30 minutes long, but it somehow felt shorter (and a tad impersonal, though the lady was outwardly friendly). If you've never interviewed before (like me) practice giving fast and concise answers so you're not thrown off. The focus was on behavioral questions, and I was talking to someone who specializes in recruiting. Just keep your audience in mind when answering and try to make your answers show why you stand out.

The hiring process consists of a HackerRank home exam, followed by three technical interviews covering LeetCode-style problems and system architecture. Once this is done, you will have a final HR interview.
