Interview
Two technical phone interviews back-to-back with assistance through the entire process via recruiter. Interviews were focused on algorithms and data structures. Each phone interview had 2-3 questions and each were expanded on.
I applied for the position online. A recruiter reached out and scheduled two back to back phone interviews. The first one was behavioral and included a code reading portion, and the second one was a technical coding question.
Short essay responses included with resume and then 2 back to back 45 minute interviews, both technical questions. Nothing very complicated (certainly not the level you get for the real software engineering internship) but they're still looking for smart people who absolutely know their stuff. It's important to review your computer science courses and understand fundamentals, but don't expect some crazy question from Leetcode to pop up.

Interview
Applied online and heard back about two weeks later. There were two technical phone interviews, 45 minutes each. Interviewers were super friendly. The interviews were mostly technical, and the second interviewer asked a few questions about my resume.
