💡 Pro Tip: PrepLounge offers access to over 800 (former) management consultants from top firms like McKinsey, BCG, and Bain, who are ready to help you perfect your interview technique.
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, What you’re describing is actually very typical at this stage. You’ve only done a few cases, then switched to drills — it feels like you’re getting worse, but in reality you’re just becoming more aware of what good structuring looks like. A couple of thoughts that might help you get unstuck. First, the inconsistency (6 → 3 → 2) is not unusual. Structuring isn’t a “memory skill,” it’s a thinking habit. Until that habit stabilizes, your performance will fluctuate. The core issue I usually see is this: people try to be MECE and “structured,” but they don’t start from the question itself. Before writing anything, force yourself to pause and ask: what exactly am I trying to figure out? Then: what would need to be true for me to answer that? Your first-level buckets should come from that — not from memorized frameworks. If they don’t directly answer the question, they’ll feel off. Second, don’t try to fix everything at once. That’s what creates the feeling of being stuck. If I were you, I’d narrow the focus: for a few days, only care about getting the first level right. Nothing else. Are your buckets directly linked to the objective? Are they non-overlapping? That’s it. Only once that feels more natural, move to the second level. Third, be more deliberate in how you review drills. After each one, instead of just looking at the score, ask yourself: did my structure actually answer the question? did I miss an obvious driver (like price/volume, revenue/cost)? was I too generic? If you can’t clearly diagnose it, that’s where you’re blocked. Also, don’t stay only in drills. They help, but they don’t fully translate unless you apply them in real cases. Try to mix in a couple of full cases and consciously focus on your structure at the start. On timeline: you’re early enough that this is very fixable. Even with some inconsistency, a few focused weeks on structuring can change things quite a bit, and you still have time until September. If I had to simplify it: you’re not stuck — you just don’t have a consistent method yet. Build from the question, fix one layer at a time, and review your mistakes more deliberately. That’s usually when things start to click. Best, Soheil

Hi, You should expect an operational, finance-heavy case, not a classic strategy one. The focus can probably be on liquidity pressure, working capital optimization, and short-term cash levers Be ready to move comfortably across the balance sheet and cash flow, e.g. receivables, payables, inventory, and how to quickly unlock cash and prioritize concrete actions (e.g. renegotiating payment terms, reducing DSO, inventory liquidation). I’d prepare by practicing cases where the goal is “improve cash in the next 3–6 months”, and make sure you can structure answers in a very practical, action-oriented way rather than staying high-level. Good luck with it and if you want to deep-dive feel free to DM me. Regards, Franco

Hi Lucia, I’ve been in your exact shoes: an absolutely first-gen student, no budget (I invested time but no money in my interview prep), and still made it to BCG and stayed for 10 years. So let me be clear: you don’t need money or a special background to get in. Right now, with one week left, keep it simple and consistent. There are several free resources on the internet to improve your logic and mental math: daily drills are important, but you don’t need anything fancy, just repetition and timing. For the case prep, I’d focus on what actually moves the needle. Do a lot of practice with other people. Once you know the basics, improvement comes from exposure: different partners, different styles, different mistakes. That’s what builds real instinct. And on the confidence side: the feedback you got from BCG matters. You’re closer than you think; you just need sharper execution under pressure. If you want, DM me and I can point you to a few free resources. Regards, Franco
Good question, and your diagnosis is already half the answer. The fix is a discipline to anchor the tree to the actual question asked. Three things that helped my candidates the most: 1. Start from the objective equation, not from drivers Before writing any branch, restate the objective as a math equation. "Grow revenue from existing customers" = # customers retained × ARPU. That single line forces you to stay inside the revenue engine and rules out competitor/product branches that do not map to the equation. If the branch does not multiply or add into the objective, it does not belong in the first level 2. Use 2 trees, not 1, and pick consciously Profitability tree when the question is quantitative and the equation is clean (revenue, cost, margin) Root-cause tree when the question is diagnostic ("why is X happening") and you need market, competitor, internal lenses The low-cost entrant case is a root-cause case dressed as a margin case. Structure: why is margin dropping (price vs cost vs mix) → then why is price dropping (competitor move, customer switching, channel pressure). Profitability first, root-cause second, nested 3. Drill: 20 prompts, 3 minutes each, structure only Take 20 prompt one-liners from Casebook or PrepLounge. For each, write only the equation and first-level branches in 3 minutes. No second level, no analysis. Do 5 per day for a week. You will stop reaching for templates because you will have built the muscle of deriving level 1 from the objective itself The second level comes naturally once level 1 is tight. Most weak trees are weak at the top, not the bottom. Happy to review a few of your trees if useful
Hey, Your doubt is logically correct, and you actually spotted something that sounds weird: if the average visits are 10 a year, why are customers spending 1200$ for unlimited visits rather than just 800$ (i.e., 10 times the $80 single entry ticket)? However, the reality is that it is not uncommon in this type of businesses to see these situations. People often overestimate how often they will use a season pass. Let's use these assumptions: A few season ticket holders might do only 1-2 visits a year (e.g., they move to another country, they get hurt early in the season, they get too busy with work). Let's say 15-20% A few others might get close to the 8 "threshold" (say 6-7 visits): when you buy the season pass, you definitely expect you'll ski much more than you actually can (even without injuries or work issues). Let's say 40-45% Lastly, a few others will get their full worth of 15-20 visits. Let's say roughly the top 40% If you compute the numbers above, you'll see that (0.18 × 1.5) + (0.42 × 6.5) + (0.40 × 17.5) = 10.0 average visits. We can discuss of whether my percentage assumptions are correct or not: I picked on purpose some numbers that would yield a 10.0 average to be consistent with the case (and I agree with you: the true average might be slightly higher than 10). However, you can see how we are not too far from a real-case scenario! Hope this helps! Tom
Hi, happy to share a few tips that work well for RB specifically. 1. Lead with the "why RB" in the first line, not the last Most candidates open with "I am a X year student at Y university applying for Z." Skip it. Open with the specific reason you want Roland Berger over MBB or Big 4. RB readers screen for genuine interest because they lose too many candidates to MBB late in the process. One sharp sentence on what attracts you to their European heritage, their industrial/automotive depth, or a specific recent study they published goes a long way 2. Structure the body in 3 paragraphs, each with one proof point Paragraph 1: why consulting (one experience that proves you have tested it, not just read about it) Paragraph 2: why RB specifically (a project, a partner you met at an event, a sector focus) Paragraph 3: why you (one quantified achievement that shows analytical rigor or leadership, not a list) One proof per paragraph. No CV repetition. The reader already has your CV next to the letter 3. Quantify everything you can "Led a team" is weak. "Led a team of 5 to deliver a market entry analysis for a EUR 2M client in 6 weeks" is strong. RB screeners are ex-consultants, they read for numbers and outcomes 4. Cut every adjective "Highly motivated", "passionate", "dynamic" add zero signal. Replace with a fact that proves the trait. If you cannot prove it, drop it 5. One page, 4 paragraphs max, no walls of text Aim for 250 to 300 words total. Recruiters spend 30 seconds on a cover letter. Make every line earn its place Happy to review a draft if you want a second pair of eyes
Hi, First of all, congrats on the invitation! The SHL General Ability test is pretty standard expect numerical, logical, and verbal questions under tight time pressure. Biggest tip: speed matters as much as accuracy. You won’t finish everything, so don’t get stuck; skip and come back. For prep, just do a few timed SHL-style practice tests (you can find several sources on the web) to get used to the format; the goal isn’t to learn new math it’s to think quickly and stay calm under pressure. Hope it helps Franco
Hi, My perspective may be biased because I am a coach, but I’d at least try one session if budget isn’t a constraint. The first session usually has the highest ROI; a good coach will quickly pinpoint your gaps, give you concrete fixes, and help you structure a clear prep plan. After that, the marginal value drops, so you don’t necessarily need many sessions. It’s also a good way to test whether coaching actually adds value for you before committing further. This applies to both the chatbot and cases, but even more for cases, where self-assessment is tricky. If you don’t go for coaching, the next best option is doing a high volume of live cases with partners, not just reading alone. You need the pressure, the interaction, and to get used to verbalizing your thinking. Hope this helps. If you want to discuss the pros and cons of a coaching session together, feel free to DM me.

Do MBB & tier-2 firms (EY-P, Kearney, Oliver Wymann) differ a lot country to country in terms of hiring standards?

If you mean the process — they can differ in the details but not in the overall process. You'll always need to do cases and some personal fit interview, but they can differ for example in the number of interviews or whether they add an upfront online test or not.If you mean the quality of profiles they are hiring — officially they do not differ. They look for the same profile, toolset and qualities - the job is very similar across countries. However, there can be differences due to: Country-specific requirements — the main ones being language and visa, but there might also be preferences for certain educational or work paths. Example: In France, they seem to prefer profiles from the Grande École education system, while in Germany grades take higher importance than specific universities. Demand-supply balance — countries might have an imbalance in supply and demand of applicants, making it at least statistically (and potentially perceptionally) harder or easier to land a job. Example: Switzerland is notoriously hard as a German or French speaker despite both speaking a local language, but the country is small and supply of applications is high; Middle East and Africa have had more demand for people than locally available in recent years, so a lot of foreigners landed jobs there (whether that lowered the barrier would be a heated discussion😉). Different positions — there are roles and programs specific to a country. In some countries you can more easily find a job in consulting after just a bachelor's degree, while in others they require a master's — the difference is they offer entry roles at the respective level.I would say in most cases you have the best odds in your home country as that's what most prefer, but there are exceptions in certain situations or countries where you might have a good chance.Hence, for a more nuanced answer, we would have to look at your specific situation and the countries you consider.
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.
