I had the nicest interviewers! There was a technical interview and a behavioral interview. The technical interview went over basic statistics (central limit theorem, definition of a Normal distribution, p-values, and t-tests). They also asked about your familiarity with SQL and Tableau but didn't press too much into technicals. The behavioral interview was a standard behavioral interivew.

Received a call for a phone screen about 2 months after I applied. Was then prompted to schedule interviews with senior employees at Discover working on the Data Science team. Questions are all behavioral. A lot of questions on how you work in a team so have a couple of experiences where you had worked in a team ready. Interviewers are interested in what you have to say and the interviews are conversational. Not too much emphasis on technical skills but they do ask about your experience so make sure you talk about your technical skills then. My interview took place during the pandemic so everything was done virtually. I believe interviews are normally conducted in-person at the headquarters in Chicago.
