San Francisco, CAPosted Oct 2025 · Candidate report, summarized by Dataford

I went through an average process that felt more conversational than presentation-based, with behavioral questions woven in and cases requiring graph reading, over roughly a few weeks.

Behavioral then case (single structured interview block) — I was asked about teamwork/leadership experiences and then moved into the case.
Case discussion style — I read and interpreted graphs and walked through my reasoning as a dialogue.
Format nuance — time blocks were laid back, emphasizing how I’d think rather than delivering a polished slide deck. Outcome: I didn’t receive an offer, but I left with a strong sense that speaking out loud and staying calm carried a lot of weight.
