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.

BCG was the best experience I never want to have again. If I went back in time, I would 100% do it again. But I will never do it again in this lifetime. It's the marines. You become your best professional self there. The training, the learning, the network, the brand, the experience, the people. It's up to you to decide if it's worth it. I highly recommend you read my consulting survival guide Here are a couple of snippets from that guide, based on what you've said: 1) This job is inherently stressful, and you are not going to be the first person to struggle with stress. Consulting firms have mechanisms in place to try to keep consultants from burning out. If you are struggling, reach out early. 2) You need comrades - your people for the really good and the really garbage days. Find them and stick to them. 3) There will always be pressure, but not every task will make or break the bank. If the success or failure of the project relies solely on the one slide you're making, there are bigger issues going on. 4) Keep a one-page version of the case story up-to-date every couple of days. 5) Always bring solutions, not problems. 6)You learn so much more when you are fully transparent about what you don't understand. 7) You will do your best work once you are okay with being fired. 8) Your Project Lead/Principal is not inside your head. Learn how to communicate and guide their attention to what they need to know. Work to their style and your life will be easier. 9) You have to stand up for yourself. And people will respect you for it (98% of the time). 10) People's perception of your performance is just as important as your performance. 11) Communication is as important as content. Communication isn't what you say, it's what they hear. 12) Being good at the qualitative aspects of consulting (presentation, communication etc.) is significantly more important than being good at the analysis/excel/quantitative side of consulting. 13) Consulting is a confidence game. Always have a strong opinion, lightly held.
Short answer: it depends on the office and even the specific role, so there isn’t one fixed test for Germany. From what people have been seeing recently, both SOVA and TestGorilla are still used. There’s a slight trend toward TestGorilla, but SOVA definitely hasn’t disappeared. TestGorilla is more of a classic timed test with numerical and logical reasoning, a bit like GMAT style under pressure. SOVA is broader and can include reasoning, situational judgment, and sometimes personality or video elements. So realistically, you could get either. The safest approach is to prepare for timed numerical and logical reasoning, since that covers the core of both. If you want, I can give you a quick prep plan depending on which one you get. best, Alessa :)

Hey Hyun, No worries! You are not the only nervous college student -- most of us on PrepLounge either are or were nervous college students, otherwise I'd personally have chosen a career path as a yoga guru :) Let me share my perspective on your 5 questions, coming from someone who has worked with many Undergrad coaches at Berkeley: 1. A Live Partner is 100% non-negotiable, but the good news is that you don't need to be part of a Consulting Club. 80-90% of European MBB Analysts have studied casing on PrepLounge, you'll find a ton of partners here! 2. STEM background: not a big problem per se, you just have to study some financial basics (e.g., P&L, ROI, NPV) and read a ton of cases to get you up to speed. I have a few docs on how to build 'industry savviness' that might help you understand business logics and market dynamics in specific industries. DM me if you are interested! On your resume, the question is how you adapt that -- but it's doable if someone who has worked in consulting (friend, Alum, coach) helps you :) 3. Referrals are very important (more context here: https://www.preplounge.com/consulting-forum/how-do-referral-work-24701). Also, mass-applying is not a strategy because the target companies are typically from 8 to 15. Try to meet them on campus, or set up coffee chats with Alums :) 4. Fit interview: this is definitely 2x harder than Tech (I have seen both worlds). The reality is that consulting is much more of a 'storytelling' business than Big Tech, and so they will test you on how you can convey your personal story. If you are good with numbers and can build business logic, the Fit is the area where a coach can help the most! 5. Timeline: if you are willing to truly commit (say 3-5 hours a day), I think you can get ready in 1.5-2 months or so. What's missing from your questions? The reality is that Consulting recruiting for US undergrads is an incredibly competitive market, only marginally better than Tech SWE. A lot of folks do everything they can (i.e., great college, consulting clubs, pro bono consulting activities, business internships) and only end up with offers from small-name boutique firms. How does this work? A ton of luck in getting the recruiter to pick your resume from the pile (although, you can definitely improve your resume and make it more tailored). If you have an interview, then that's where you can make the difference -- it's 100% doable if you build the right plan with the right advisor (a friend, an Alum, a coach), if you put in the work, and if you find someone who gives you real, honest feedback Good luck! Tom PS: Feel free to book a 15-min intro call with me. It's free (no commitment) and I am always happy to help a nervous college student, because I was in your shoes a few years ago :)
Mckinsey Quantum Black SWE Virtual Problem Solving Case + Personal Experience Interview

hey there :) congrats on passing the pair programming round :) for the next step in QB SWE track, it’s usually not a traditional business case. the “Virtual Problem Solving Case” is more like a mix of light system design + applied coding thinking, often framed around real product or data problems. think questions like how you would design a simple end to end feature, structure data flow, or improve a basic system, rather than consulting-style profitability cases. the “system design” part is typically entry level, so they are not expecting deep architecture knowledge, more clarity on how you break down requirements, data handling, APIs, scalability basics, and trade offs at a high level. the “Personal Experience Interview” is more behavioral, focused on how you work in teams, handle ambiguity, and your motivation for engineering in consulting, so be ready with structured STAR stories. overall it’s still quite practical and problem solving focused, just more technical-context driven than business case driven. best, Alessa :)
How to approach ambiguous multiple-choice questions (MCQs) questions in BCG Case Chatbot?

Hey, Let me be super-honest with you: I spoke about this with a few MBA friends who now work at BCG and they told me that they don't love the chatbot either, so you are not alone in complaining :) What I would do is trying to write down the clear logic link between the different risks and the investment. Here: Regulatory risk: if the regulator limits this ex-post (e.g., up to a certain market share, or limiting usage), the value of the investment is likely to be reduced. Very clear link -- good! Can we falsify this? If regulators set limitations, our investment is not likely to be reduced. I can't -- this confirm my selection Interdependency risk: if the other operator changes their strategy, exits a specific geographical market, etc., the investment is likely to lose value (or, I might have to cover more OPEX). Very clear link -- good! Can we falsify this? If the other operatore changes their strategy, our investment is likely not to be reduced. Well, it technically can, but I really have to find edge cases to falsify the hypothesis (e.g., we have more 5G supply for our clients and we can monetize this) -- I would keep it Risk that one company may not want to continue investing due to lower calculated profitability: this feels very similar to the interdependency risk. Very clear link (as above) and hard to falsify -- same as above Decline in phone sales market: What matters is the evolution of the demand of 5G, that does not logically require phone sales to grow. Weaker link -- I would not select this! Can we falsify this? If the phone sales decline (e.g., people do not buy iPhone 18 but stick to 17), the 5G usage is not directly impacted. I say yes -- so I would confirm the 'no selection'. Again: overall, I agree with you on how this exercise can not be treated deterministically (i.e., prompt x always and only leads to y in any case and with any realistic assumption). However, I still think that the idea of writing down the relationship and trying to falsify it might help :) Best, Tom
BCG - how long to hear back from Round 1 & how to prepare for Round 2?

Hi, If you are applying to standard positions, you should typically hear back within 3–10 days, in some cases, it can stretch to 2 weeks. For niche or senior roles (when often there is only one spot available) even 3–4 weeks if they’re closing the full interview cycle. For Round 2, I've done plenty of them myself as an interviewer in BCG. Don’t expect a completely different format. In most cases, it’s very similar to Round 1, just with a higher bar (I used exactly the same cases in both rounds). That said, with more senior interviewers (e.g., MDPs/Senior MDPs), you might see shorter, more qualitative cases or a heavier focus on fit, especially if your casing was already strong in Round 1. So preparation-wise, focus on doing the same things, maybe with a higher focus on cleaner structure, sharper insights, and more natural communication rather than trying to learn a new format. If you want to discuss further feel free to DM me. Regards, Franco
Hello! My suggestion is: keep messages brief, find a connection (same city, university, or an article they wrote), explain why you are interested in their firm/work, and don't ask for the referral upfront in a way that might be perceived as too direct (e.g., "Hey! I need a referral for your firm ..."). Don't worry, consultants know the game and will help if there's genuine interest :) FYI: for junior applicants, a referral simply means an insider saying, "I trust this person; they deserve an interview." However, seniority matters: a Senior Partner referral practically guarantees an interview unless your CV has red flags. Best! TomPS: Coffee chat culture (i.e., connecting to discuss your interest in working at someone's company) varies globally. It's generally harder in Southern Europe and MENA, but much more common in Northern Europe and the US, which will impact your response rate.
Big 4 M&A to London MBB: Optimizing the LBS MBA Timeline (2 vs. 4 Years Exp)

Best answer by
Tommaso
Hi Anonymous, thanks for the question!Speaking from what I've seen with many MBA applications to MBB (both in the US and the UK), here is the reality of your situation: The "2 vs. 3 Years" Dilemma: From a recruiting standpoint, the difference between two and three years of Big 4 experience is very minimal. You are risking over-optimizing a detail that won't really move the needle for MBB recruiters. Seniority and Leveling: Everyone generally starts at the standard post-MBA level (Associate at McKinsey, Consultant at BCG/Bain). I have almost never seen anyone enter at a higher role post-MBA unless they are an experienced hire in a highly critical sector facing a talent shortage—and those candidates usually bring 8+ years of experience to the table. What Actually Moves the Needle: If you want to stand out for PE/M&A practices, what would make a massive difference is landing a role at a Private Equity fund. I know it's incredibly difficult, but even just one year (or a pre-MBA internship in PE) adds immense value. Very few candidates have actual pre-MBA PE experience, so this would make your CV genuinely differentiated. A Candid Reality Check: I'll close with a note of caution. I know many people who have tried to make the exact switch from Big 4 to MBB via an MBA, and realistically, few succeeded. The competition is fierce, and Big 4 profiles aren't always seen as highly differentiated when stacked against candidates with deep, specific industry expertise (e.g., 5 years in specialized engineering, a former PM at Google, or someone with a heavy industrial background).An MBA absolutely gives you a shot, but I highly recommend verifying the conversion rates. Spend some time on LinkedIn searching for people who have successfully made this specific Big 4 -> LBS -> MBB transition. From my experience, it's a tough pivot, so you want to go in with your eyes wide open and a clear strategy to stand out. Best of luck!
Has anyone noticed consulting firms being hesitant to consider candidates due to potential future visa requirements?

Hi, Overall, this sentiment is fairly widespread across most industries in the US right now, so you're not alone in noticing it. I am assuming you are referring to the US, since I have not seen or heard changes across Asia and Europe That said, from what I've seen in the US, the larger consulting firms (MBB and Big 4) have continued interviewing and hiring international candidates at a fairly consistent rate. They tend to have the infrastructure and experience to manage the complexity that comes with work authorization. For smaller firms, there does seem to be a growing trend toward "simplification" -- they're often less equipped to handle uncertainty, so they may shy away from candidates whose situations require more planning ahead. It's less about you and more about their own limitations. Good luck with your search! Tom
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.
