Requires a pretty intensive case study where you write an op-ed for one of their clients (24 hour deadline) before you can interview. First interview is a screening with the hiring manager, who is friendly but a bit unprofessional. I didn't advance to the next round, but I think the second round interviews are with managers.

It wasn’t difficult, a few rounds. Started with HR and then moved to more internal people. Overall, everyone was very nice and seemed excited about the opportunities at this company
