This was a pretty long process of 2 online assignments, 1 phone interview that ran over 2 hours and 1 onsite interview. The online assignments were pretty straightforward, though they seemed completely unrelated to the job or the company. I was asked to write about different types of cognitive bias. The phone interview was pretty intense, and I was grilled for about 2 hours to keep brainstorming more and more solutions (even though some of my proposed ones were already correct). The onsite interview was very easy, I was given a bunch of logic tables to compute and asked a few standard personal background questions.
