Across these McKinsey Business Analyst accounts, one pattern repeats consistently: nearly every interview pairs a Personal Experience Interview (PEI) with a business case, rather than separating behavioral and case rounds. Some candidates started with an online test, described in one account as a game-style assessment and in another as quite hard, before live interviews began. Reported processes ran from two rounds, each with two back-to-back interviews, to three rounds. One account described a first round followed by a superday with three interviews. Interviewer seniority tends to climb along the way, from engagement managers early on to associate partners and partners later.
PEI questions draw on familiar McKinsey themes. Candidates were asked about:
Interviewers often stayed on one story through multiple follow-ups. On the case side, one candidate described a consistent sequence: structuring, then exhibit analysis or brainstorming, then a quantitative calculation. Others faced a profitability decline at a coffee shop chain and a case on improving a software business. Several noted that the math was where pressure peaked, and that later-round partners pushed harder on assumptions than earlier interviewers.
Outcomes were mixed, and one rejected candidate appreciated receiving feedback. Timelines also varied, from roughly six to eight weeks in one account to more than four months in another. Prepare PEI stories with enough depth to survive repeated follow-ups, practice case math until it feels automatic, and rehearse defending your assumptions out loud.

Synthesized from candidate reports. Individual experiences may vary.
Some candidates report starting with an online test. One account described it as a game-style assessment, and another found it quite hard. Not every account mentions this stage. One candidate also had a separate HR conversation about motivation and background.
In the first round, candidates typically report two interviews, each combining a Personal Experience Interview with a business case rather than treating them separately. PEI questions draw on themes such as conflict, leadership, tight deadlines, and convincing others. The case portion usually involves structuring the problem, interpreting exhibits or brainstorming, and working through calculations out loud.
Subsequent rounds, sometimes a superday of three back-to-back interviews, repeat the same PEI-plus-case format. Candidates report rising intensity as interviewers become more senior, such as associate partners and partners. Several described later interviewers pushing harder on assumptions and math than in the first round.
Reported cases included declining profits at a coffee shop chain and suggestions to improve a software business, alongside classic cases drawn from McKinsey's case database. Candidates repeatedly singled out the math and financial calculations as the most pressured part. Interviewers expected them to stay structured and defend their assumptions when challenged.
Candidates report different end-to-end timelines, from about six to eight weeks in one account to more than four months in another. Outcomes were mixed, and one rejected candidate noted that the rejection came with feedback.
