How Merck & Co. interviews work
Your CV and cover letter are reviewed against specific criteria. Boutique firms often read applications personally. Clarity, specificity, and a coherent motivation for this firm matter from the first line.
Two to four rounds of case interviews combined with personal fit questions. Formats vary — some are interviewer-led, others candidate-led. Structure your thinking out loud and show you can hold a clear thread through complexity.
Final conversations with senior leaders, often less structured and more genuinely conversational. They're assessing whether they'd trust you in a room with a client. You're assessing whether this is the right firm for you.

Tips for your Merck & Co. interview
Consulting interviewers want candidates who think like business people. Follow major industry trends, significant M&A activity, and the firm's published work. Reference specific examples naturally where they add credibility to your answers.
Case interviews reward candidates who are comfortable structuring problems in real time. Interviewers aren't looking for a perfect answer — they're watching your reasoning process, how you handle uncertainty, and whether you can be directed.
Many candidates win the case and lose the offer. Fit interviews assess whether you're the kind of person clients and partners will trust. Preparation, genuine enthusiasm, self-awareness, and the ability to hold an engaging conversation all contribute to the decision.
In case interviews and behavioral answers alike, lead with your conclusion and support it with evidence. Top-down communication is the consulting standard. Candidates who build to their answer at the end score markedly lower on communication.
Case interviews are the centrepiece of consulting recruitment. Learn profitability, market sizing, market entry, and M&A frameworks. More importantly, practice applying them to novel cases — not just repeating memorised structures. Interviewers score your thinking process, not pattern-matching.
Solo case prep has real limits. Social pressure, timing, and real-time redirection are fundamental to the actual interview experience. Find a practice partner and run through cases — the feedback from a real person is impossible to replicate alone.

Give me an example of when you challenged your own initial analysis.
I was working on a market entry analysis for a UK consumer brand considering expansion into Germany. My initial hypothesis, based on market size data, was that Germany was the strongest entry market in Europe.
I needed to finalise my recommendation within a week.
When I modelled unit economics more carefully, I found that the German retail market had significantly higher promotional spend requirements and lower margins than the UK baseline. I ran sensitivity analysis on three margin scenarios and found that under realistic conditions, Germany would take 4.5 years to reach payback — versus 2.1 years for the Netherlands, which had a smaller market but a more favourable trade structure. I updated my recommendation and documented the assumptions clearly so the client could stress-test them independently.
The client chose the Netherlands. At the one-year mark, the business was tracking ahead of the 2.1-year payback model. My manager used the analysis framework as a template for subsequent market entry work.
Frequently asked questions
What is a case interview?
A case interview presents a business problem — typically a client challenge — that you structure, analyse, and develop a recommendation for in real time. They're the centrepiece of consulting recruitment and assess structured thinking, commercial judgement, and communication quality simultaneously.
How competitive are consulting graduate programmes?
Extremely. McKinsey, BCG, and Bain each offer a few hundred analyst places globally per year and receive tens of thousands of applications. Acceptance rates at top firms are typically under 1–2%.
What makes a strong case interview performance?
Strong candidates structure the problem clearly before diving in, communicate their reasoning as they go, handle curveball data without losing composure, and arrive at a clear recommendation. The process and communication quality matter as much as the final answer.
What is the McKinsey Problem Solving Game or BCG online assessment?
Several leading consultancies use proprietary online assessments — McKinsey's Problem Solving Game tests decision-making and reasoning; BCG uses situational tests. They're not case interviews but act as early filters. Practice examples are widely available and worth completing before your actual assessment.
Do I need a business or finance background for consulting?
No. Consulting firms hire across all disciplines — STEM, humanities, social sciences, law. What they assess is how you think and communicate, not what you studied. Basic numeracy and commercial awareness are expected from all candidates regardless of background.
