Interviewed for a fairly senior IC (individual contributor) role. Was referred by an acquaintance working in the group, definitely accelerated my getting an interview. Initial round was a phone screen by the hiring manager (Director level?). Next round was on site, half-hour 1:1 interviews with maybe 5 different people, including other PMMs as well as cross-functional partners (PM, Emerging business). Different interviewers were assigned different "attributes" as focus areas: e.g. Strategy, Marketing, Leadership skills. Interviews were primarily behavior-based (vs. elaborate case studies) - e.g. "tell me about a time when..." Multiple interviewers asked me about leadership style / what feedback I had gotten from team members. There were a couple mini-case study type questions (e.g. "Let's explore business issue X together..."), but they were modest (e.g. 5-10min) compared to what you would see in a management consulting interview. No group interview or presentation type formats.
