What Are the Key Advantages of Practicing With a Coach?
Personalized Feedback
One of the primary benefits of working with a case coach is receiving tailored feedback. Unlike general preparation methods, a coach can pinpoint your specific weaknesses and provide actionable advice to improve. This personalized approach ensures that your preparation is efficient and targeted, addressing your unique needs and challenges.
Realistic Simulation
Practicing with a coach allows you to experience a realistic interview setting. Coaches who have conducted numerous case interviews can replicate the pressure and dynamics of a real interview, helping you become more comfortable and confident. This experience is invaluable, as it prepares you to handle the stress and spontaneity of actual interviews.
Insider Knowledge
Experienced coaches often come from prestigious consulting backgrounds themselves. Their insider knowledge about what top firms are looking for can give you a significant edge. They can share insights about the interview process, common pitfalls, and the specific attributes that firms value, ensuring that you are well-prepared to meet these expectations.
Structured Approach
A coach can help you develop a structured approach to solving case problems. This structured thinking is crucial in case interviews, where clear, logical, and well-organized answers are highly valued. Coaches can teach you frameworks and methodologies that streamline your problem-solving process, making your responses more coherent and compelling.
Time Efficiency
For candidates with limited preparation time, coaching is a highly efficient way to get ready. Coaches can quickly identify areas that need improvement, helping you focus your efforts where they are most needed. This targeted preparation can save you time and help you progress faster than you would on your own.
Confidence Boost
Confidence plays a crucial role in interview performance. Regular practice with a coach can boost your confidence by familiarizing you with the interview format and helping you refine your answers. Knowing that you have prepared thoroughly with expert guidance can significantly reduce anxiety and improve your overall performance.

Hi, I think that would have been your chance to highlight a strength and position yourself clearly in front of the interviewer. Saying “no” won’t kill your chances if the rest went well, but it’s not the most elegant answer; you’re leaving value on the table. A simple pivot works: “Actually yes, we didn’t touch on [X], which is one of my key strengths. In my last experience, I…” Good luck, Franco
I get this question a lot, and I think there’s a common misunderstanding here. A hypothesis is not a guess. It should be based on some evidence or logic, not something you “throw in” at the start. So for your two scenarios: I wouldn’t do either. Stating a hypothesis right after reading the prompt or right after your structure is, in most cases, just guessing; and that doesn’t add value. At the beginning of a case, your job is to: clarify the problem build a solid structure Not to predict the answer without data. The only exception is if you have very specific prior experience in that exact industry; then you can say something like: “In similar situations I’ve seen X being the main driver, so I’ll keep that in mind as we analyze.” But even that should be light, not a strong claim. The right moment to use hypotheses is during the analysis. For example, after looking at a chart or doing a calculation, you can say: “Based on what we’re seeing, I’d hypothesize that the issue is coming from X rather than Y.” That’s much stronger because it’s grounded in evidence. For a profitability case, a good hypothesis would be something like: “Given revenues seem stable and costs have increased, I’d focus on cost drivers as the likely root cause.” Bottom line: don’t force a hypothesis at the start; build it as you learn more. Hope this helps, Franco
Hi Anonymous, yes, it’s absolutely possible — your profile is actually quite relevant. Coming from Centrale Lyon with a strong GPA is already a very solid base. On top of that, your internships in supply chain are not a weakness — if anything, they can be a strength, especially for: operations consulting transformation projects even strategy roles with an operational angle What matters is how you position them. Right now, you shouldn’t think: “I didn’t do consulting internships” But rather: “I’ve worked on real business problems (planning, demand, operations) in top companies” That’s valuable. A couple of things to focus on: 1. Position your experience in a consulting way In your CV and interviews, highlight: problem solving (what was the issue?) impact (what did you improve?) ownership Even in supply chain roles, there are always elements like: optimizing processes improving forecasts reducing inefficiencies That’s very close to consulting work. 2. Be clear on your story You’ll need a strong answer to: “Why consulting now?” Something like: you’ve seen operations from the inside you now want broader exposure and more strategic impact 3. Prepare interviews properly At your level, this is often the real differentiator. Good candidates get rejected because of: weak structure lack of case practice So make sure you: practice cases consistently get comfortable with math and structuring 4. Be realistic but ambitious MBB is competitive, but your profile is definitely in range. Also apply to Tier 2 — they’re great options and often a very good entry point. Overall, you’re in a good position. You don’t need a “perfect consulting background” — you just need to present your experience well and perform in interviews. If you want, happy to help you refine your CV or practice cases.

Good question; you’re targeting a different segment of consulting than typical strategy consultancies (McKinsey, BCG, Bain), which changes a few things. First, your role is going to be quite specialized and more “operational”, not purely strategic. Because of that, local language becomes much more important than in firms like McKinsey, BCG, or Bain, where English is often enough. In supply chain / planning roles, you’re more likely to interact with operational teams who may not be fully comfortable in English, and that can be a real constraint. On geography, the UK and Ireland are the most straightforward options. Beyond that, the Netherlands and the Nordics are probably your best bets, as they tend to be more open to English-speaking profiles. Outside of these, it becomes significantly harder without the local language. On the age point, I wouldn’t worry too much in your case. Age can be a concern for generalist, entry-level consulting roles, but for specialized roles like yours, expertise matters much more than age. In fact, your 8 years of experience is likely a competitive advantage, not a drawback, compared to younger candidates with less hands-on exposure. So overall, I’d focus on: targeting the right geographies (UK, Ireland, Netherlands, Nordics) positioning yourself clearly as a specialist, not a generalist switcher Hope this helps. Franco

Congrats! Regarding your last question, on whether the case will be QB-specific or generic, do ask the recruiter directly. They're best positioned to tell you. On the personal fit, read the guide that McKinsey sent you and you might also want to consider this targeted PEI course I've built which lots of candidates are finding useful: • • Video Course: Master the McKinsey PEI Best, Cristian
I strongly recommend you reach out to the recruiter. These things can change pretty quickly, so it's worth having the info straight from the source. That aside, make sure that you target several firms at once. Targeting just one can be problematic because bad luck can work against you. You might find it useful to read this guide that walk you through how to build an application strategy: • • Expert Guide: Build A Winning Application Strategy Best, Cristian
Hey Anonymous, Always happy to help, but we need more context. I don’t see the insurance/bus section in the “related case” at your question’s link. Do you mind sharing more? Best, Tom

Hi, 8–9 weeks isn’t the norm, but it doesn’t signal a rejection either. If they had decided to pass, you would’ve heard by now. More likely, something internal (capacity, timing, office needs) or external slowed things down and your application is still being processed. Best move now: send a short, gentle email to recruiting asking for an update. Hope it helps Best, Franco
Struggling with structuring + final recommendations in case interviews

Hey there, Thanks for your question! First of all: I think you are trying to solve for 3 different problems, so let me go step by step. 1. Structuring: drills can indeed help. Try not only to build a structure, but also to communicate it (i.e., start with naming the buckets, then get into each bucket's bullet, be strategic on what to say regarding each bullet -- some of them are more important than others depending on the industry/company context, and on some of them you might want to showcase). Record yourself and then play Devil's advocate: try to find at least 2-3 ME issues and 2-3 CE issues. You'll get better, we've all passed this phase :) 2. Case communication: # of solved cases matters, but you might need a coach. This is where the sheer number of solved case matters the most. Keep in mind that the communication for, say, qualitative questions follows different rules than, say, maths. If you are not a natural communicator and don't see improvements after 5-10 cases, that's the area where a coach might help the most -- I think 70% of the work I do with my candidates is about communicating better concepts/ideas that they already have in their minds. 3. Recommendation: just pick a structure and iterate. This is the easiest part. I suggest you start following a simple structure, see the example below: A two-line recommendation. Think of this as the title of the final recommendation slide (and yes: in MBB, slide titles go over two lines!) At least two points of supporting rationale. Ideally, one quantitative and one qualitative Risks and mitigations: impossible to be exhaustive, focus on the top 1-2 Immediate next steps: here, you should be pragmatic -- what can they do in next week, and in the next month? Good luck on your journey! Feel free to DM me to continue this conversation with a free 15-min intro call :) Best, Tom _____________ Recommendation Example Leading Sentence: MediLink should implement a new inventory strategy to release NWC and improve commercial performance to generate $X in additional profit. Supporting Rationale: Quantitative: Increasing Product A's service level to YY% generates €X.0M profit against €0.XM in holding costs (a >10× return). Reducing Product C’s over-servicing simultaneously releases tied-up NWC. Qualitative: The current uniform policy misallocates capital by over-serving low-value Product C and starving high-value Product A. A differentiated model aligns Ops with Sales objectives. Risks and Mitigations: Key implementation risks are IT system changes and team change management. We recommend mitigating this through a phased rollout and clear day-one KPIs. Immediate Next Steps: Next week: Reclassify SKUs to correct categories and define differentiated service-level targets. Next month: Test the new model on top Product A SKUs (with IT update), measuring KPIs weekly to validate the business case for full rollout.
Questions about market size are frequently asked in case interviews in consulting because they require a blend of logic, mathematics, and common sense. They can be asked as standalone questions or as part of a larger case. Applicants who are familiar with market sizing questions can really perform here.
Market entry cases are one of the key issues in the consulting industry and present consultants and firms with unique challenges and opportunities. These cases require deep analysis and strategic planning to successfully enter new markets.
Brainteasers are a type of problem that focuses on a single issue rather than complex business cases. They require out-of-the-box thinking, logic or math skills and can take the form of riddles, word problems or visual puzzles. These tasks are designed to test your problem-solving skills, analytical thinking and ability to remain calm under pressure.Typical problems cover everyday life's topics and might even include unrealistic assumptions. All necessary information is usually included in the question so that further assumptions are not necessary. This article explains in more detail why brainteasers are useful in case interview preparation and how to solve them.
