I applied online. I interviewed at Keystone (New York, NY) in Jul 2026
Interview
HR call, then the first-round interview, then the writing assignment, and the final round with three interviews (different levels of interviewers). Takes them up to 2 business days to communicate the decision.
Total 4 rounds—HR screening, first round (1 case), second round (3 cases), final round with partner. The cases were open-ended compared to MBB cases, and pretty straightforward. Economics and strategy concepts tested.
Straightforward, typical management consulting style cases. I would say it took around 1 month in total. Around 4 hours of final interview, and i didn’t receive the green light. It was all on zoom
