I applied on Handshake, and was invited to two webinars before my first interview. During the first interview, it was basically just a quiz asking me about information I learned in the webinars. A big red flag was that at the end of the interview I was asked "Now that you know what we do, are you still interested in this position?" I said yes, and I went onto the second round a few weeks later. It was a two hour case interview, and the last 40 minutes were just more behavioral questions.
