The reported McKinsey & Company AI Research Scientist experience puts structured reasoning and clear communication at the center of preparation. One candidate described an initial personal conversation followed by a classic case study. Their account emphasizes explaining how they organized the problem and reached conclusions, rather than relying on flashy technical tactics. Prepare to make your assumptions, prioritization, and reasoning easy to follow as you work through a case.
That same candidate also faced behavioral questions about changing a team’s perspective and demonstrating personal impact. Build a small set of specific stories that show your role, the resistance or challenge involved, the actions you took, and the result. The report suggests that influence and clarity matter alongside analytical work.
A separate report for a related Research Scientist–Senior Analyst role described a phone screen on background and healthcare experience, then a 90-minute online assessment with Python, data science, and multiple-choice questions. It also included a technical-experience discussion of healthcare data sources and a final 45-minute SQL pair-programming task using two tables to identify cities with the best and worst donor percentages. If your background is domain-specific, be ready to discuss the data you have worked with in practical terms and to write and explain SQL live.
Evidence is limited to two candidate accounts, so the exact sequence and emphasis may vary by team and level.

Real interview reports from people who went through the Mckinsey & Company process.
The process started with a phone screen that covered my background and healthcare experience.
The next step was a 90-minute online assessment with two coding questions, one in Python and one data science question, plus 23 multiple-choice questions.
After that, I had a TEI and PEI interview. The technical experience portion focused on my background with claims data, pharmacy data, IQVIA, Symphony, and RxNorm data sources. The personal experience interview asked about a challenge I had faced in a project or non-technical experience, and I shared one of my project examples.
The final practical assessment interview was a 45-minute pair-programming SQL round. I was given two tables, donor and acceptor, and asked to find the cities with the best and worst donor percentages.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an early conversation about their background. One related research-scientist account specifically covered healthcare experience, so applicants may benefit from connecting prior work to the role’s problem domain and explaining their individual contribution clearly.
One AI Research Scientist candidate reported a classic case study after an initial personal conversation. The account emphasizes how the candidate organized the approach and communicated decisions, so practice narrating assumptions, tradeoffs, and conclusions as you solve.
A related Research Scientist–Senior Analyst candidate reported a 90-minute online assessment with one Python question, one data science question, and 23 multiple-choice questions, followed by discussion of technical experience with healthcare data sources. This may vary by team.
Candidates report behavioral questions on changing a team’s perspective, personal impact, and project challenges. One related candidate also reported a 45-minute pair-programming SQL task using donor and acceptor tables to compare city-level donor percentages.
