Washington, DCPosted Oct 2020 · Candidate report, summarized by Dataford

I interviewed for the Business Analyst role with a two-round structure where the cases were friendly but the final stage was noticeably tougher, especially as senior interviewers joined.

Round 1 (analyst-focused, brief behavioral + interviewer-led case) — Two ~40-minute interviews with a small behavioral portion followed by a guided case mixing qualitative and quantitative elements, plus time to ask questions.
Final round (superday-style, harder cases + more senior panels) — Four ~40-minute interviews and an additional Q&A; interviews included both behavioral and case components, with some interviews leaning more heavily to one or the other.
Case themes (anti-trust/collusion) — Another version of the same journey described strong anti-trust and collusion
