I applied online around mid-October and got an email from my recruiter about a week later about scheduling two 45 minute back-to-back phone interviews. I got scheduled very quickly and ended up interviewing in mid November. I'm a second year, so both interviews were technical. My interviewers were super nice and helped me out if I messed up or if there were ways to improve my solutions. I thought the questions themselves were pretty straightforward. Before your interview, your recruiter will send you slides about how to prepare, which are really helpful. I would recommend studying basic data structures and algorithms and their time complexities. I was worried that I had made too many small mistakes, but ended up getting a call from my recruiter with an offer a little over a week after interviewing. So don't worry too much about small errors, but make sure to talk through your thought process and test your code!
