It began with a phone call with HR, then a video interview with 2 attorneys, and then a final round with several more attorneys split over two days. The interviews were conversational and not too challenging. Overall I wasn't very happy with the process because a) I have never been asked to interview for an internship over so many days (including big law) and b) I was promised a response in one week. I ended up accepting a different offer two weeks later after not hearing anything.
