I got an interview at one of their info sessions on our campus. The interview was the very next day. The interview was easy, if you know your data structures you should be fine. I had an off day I guess. Got back a rejection within a week. Overall a great experience, it took one week for me to hear back from them so definitely quick and painless. Seems like a good company to work for, they have no competitors and are a late stage IPO companies so if you can get some RSUs, it will definitely be worth a lot.
