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 there, A lot of people assume fit is either “you have it or you don’t.” In reality, most strong candidates you see didn’t start out polished — they just put in very targeted practice. If I think about candidates I’ve worked with (especially those who didn’t feel like natural communicators), getting to a solid “pass” level in fit usually takes somewhere in the range of ~20 hours, give or take. Some need a bit less, some more — but that’s the right order of magnitude if the practice is actually deliberate. The key difference I see is how people use those hours. The ones who improve fast don’t try to prepare 10+ stories. They pick a handful of experiences (4–5 max) and really work them. Not just recalling what happened, but shaping them so they’re easy to follow, clearly structured, and actually answer the question. And then — this is the part most people avoid — they practice out loud. A lot. You only really notice the problems when you say your answers: you go in circles, you lose the point, you add unnecessary detail, your energy drops. None of that shows up when you’re just thinking quietly. Another thing that helps a lot (even though it feels awkward at first) is forcing some structure into your answers. Not in a robotic way, but just being intentional about how you start. For example, instead of diving into the story, taking a second to frame it: what the situation was, what you were trying to achieve, and why it matters. Once that clicks, your answers become much easier to follow — and you sound more confident without “trying” to. Also, small but important: don’t aim to sound polished. Aim to be clear. Those are not the same thing. Some of the best candidates I’ve seen are not particularly “smooth,” but they’re very easy to understand and feel genuine. If I had to boil it down from what I’ve seen work in practice: focus on a few strong stories, structure them properly, and say them out loud until they feel natural. That’s really it — but you do have to actually do the reps. Best, Soheil
McKinsey PEI: What does McKinsey mean by "People with different backgrounds" within the leadership theme of PEI

Hey Usman,McKinsey’s obsession with “diverse backgrounds” isn’t about checking boxes for nationality or culture It’s much more pragmatic. They just want to know if you can herd cats specifically, cats that have different incentives, seniority levels, or temperaments.Your Tier 2 consulting background is a perfect sandbox for this: You’ve got senior partners, junior analysts, and clients all wanting different things; that is your diversity.Don’t go hunting for a more "exotic" story; you’ve already got the goodsThe real "fail" for most candidates isn't the example they pick, but how they tell it.Just saying you "aligned the group" is a bit too generic. Showing how you used Tactics A for the skeptical CFO and Tactics B for the overworked project lead is where the magic happens. It’s all about the pivotBest,Franco
Hi there, I like that you are thinking about this early — but I’d be careful not to overestimate how much a dual degree by itself moves the needle in recruiting. Having business + engineering is definitely a strong combo. It signals you’re quantitative and also understand the commercial side. That’s attractive for consulting, tech, product roles, etc. So yes, all else equal, it can make your profile a bit more interesting. But in reality, recruiters don’t sit there and say: “this person has two degrees, so hire.” They care much more about things like: what you actually did (internships, projects) how you think and communicate whether you’ve shown leadership or impact I’ve seen candidates with “perfect” academic profiles (including dual degrees) who struggled, and others with simpler backgrounds who did very well because their experience and story were stronger. Where the dual degree does help is if you use it well. If it just sits on your CV as: “BBA + Engineering”, it doesn’t add much. But if you can say: “I’ve worked on problems at the intersection of tech and business — for example…” then it becomes much more powerful. That’s when it actually differentiates you. Also worth thinking about the trade-off. A dual degree takes time and energy. If it comes at the expense of internships, networking, or leadership experience, it might not be the best trade. So the way I’d think about it is: do it if you’re genuinely interested in that mix and want to build a profile around it — not just because you think it will boost recruiting chances. If I had to summarize it simply: it’s a nice plus, but it won’t replace strong experience and a clear story. Best, Soheil
Hey Anonymous, First of all: you are not alone, I remember how complicated it seems to face these choices at a very young age. And, from your story, it seems like you have already done a lot and are an incredibly proactive person -- kudos! However, answering to your question is almost impossible: you are comparing two institutions (Nova and UW) that frankly tend to be very similar. Both are very prestigious, they have similar rankings, they probably send a good number of students to MBB every year. Even Marketing and Management are not that different! The reality is that many other things in your life will co-determine what kind of job you will get. Getting a specific job is not a deterministic process where you can confidently say "I need to go to Uni X vs. Uni Y, because I will get a 30-50% higher change of working for McKinsey". There are too many factors (your internship, your interests, the specific needs of the office, the economic cycle, etc.) to control for. A Management program might be more aligned, but also more people will apply to MBB and so you might be less likely to stand out. The only good advice that I can give you is making a choice that you think will make you generally happier. Here, *generally* means in the average outcome, and not only in the xx% outcome where you land an MBB job straight out of undergrad. If you want to do more Strategy than Marketing/Analytics in your life, then switching might make sense if that's driven by genuine passion, maybe less so if driven by an unproven y% in improvement in your job prospects. And are you sure that your current degree gives you statistically significant lower chances of getting the work you need? When I was facing a similar choice, what helped me a ton was speaking with alumni. I was worried that my "favorite" MSc. program could have limited career opportunities, but speaking with five Alums showed me my assumption was totally baseless :) Good luck on your endeavors! Tom PS: Fwiw, keep in mind that my colleagues at McKinsey had every kind of degree: Management or Finance for sure, but also Marketing, Humanities, Design, Engineering, Biotech, etc. Also, many of them joined McKinsey much later in their life, so any choice you make you'll have more than a few opportunities to do strategy consulting.
HR asking for comp details after 2 weeks – Is an offer likely?

Hi, Given that HR is asking for your compensation details at this stage, it is very likely that an offer is coming. This kind of request typically happens late in the process, once you’ve cleared the bar That said, it’s always better to manage expectations and wait for the official confirmation, just to avoid unnecessary disappointment. But overall, this is clearly a positive signal. Regarding compensation differences between Dubai and Riyadh, I would rely on publicly available information, as I don’t have more up-to-date or specific insights to add here; others might be better placed to comment on recent packages. Hope this helps! Franco

How much would you charge to clean all the windows in Seattle?

It is one of the most popular Fermi questions and you could face it during the 1st round, when math and problem-solving skills are usually tested deeply. I will propose a quick solution, in order to give later some detailed considerations.
Let's estimate the number of windows in Seattle.
No. of residents in Seattle: you do not have to know that Seattle has almost 750k residents, but a good candidate should infer that it is a big city in the US and that can be assumed it has 1M residents.
No. of windows per residents: you are actually interested in the number of facades to clean; a small window has 2 facades, the inner one and the external one, while bigger windows have 4 or more facades. Let's assume that an average residence in Seattle has 2 people and 40 window facades. So we have 20 residential facades per inhabitant. Let's assume to have other 20 commercial window facades per resident, including e.g. bars, offices, stores.
-> 1M residents x 40 window facades, we have a total of 40M facades to clean.
Now let's evaluate the charge per facade.
Facades per hour: the time requested for a wide window of a store will be much higher than the service window of a little house. Let's assume an expert cleaner will take 1 min for a medium-sized window, i.e. 60 facades per hour.
Charge per hour: let's assume an hourly rate of $10. We should also consider the cost for infrastructures, tools, products, and insurance: let's estimate other $5 per hour.
-> in an hour: $15 / 60 facade, that gives 25 cents per window facade.
--> Therefore to clean all the windows of Seattle you could charge $10M ($0,25 x 40M).
Remember: in consulting nobody knows the number of windows in Seattle and maybe neither in window-cleaning companies :) What will be valued is not the accuracy of this type of numbers, but the reasoning you make behind them and your common sense (you should always wonder if numbers you estimate have sense or not). In addition, when you complete an estimation (e.g. the no. of residents in Seattle) you can ask the interviewer whether you can proceed with that number or she has something more accurate.
The solution proposed will be considered great and will allows you to pass the round. But in order to really crack it and impress the interviewer, you should be more curious, proactive and come up with creative considerations, potentially based on personal experience. Some examples:
When you calculate the no. of windows in town you can make some comparisons with your city, e.g.: "in Manhattan, I feel lucky with just one window at home, but I know that Seattle is more residential, houses are bigger and they usually have beautiful views on surrounding gardens and parks. Therefore let's assume an average house has 4 little windows (2 facades each), 4 medium (4 facades each) and 2 big (8 facades each)."
Think out of the box: ask the interviewer if you should also consider the car windows.
When you evaluate the cleaning speed you can say, with a bit of healthy self-irony: "A medium-sized facade take me at least 3-4 minutes to clean it. But I know to be a disaster :) I assume an expert cleaner with professional tools can handle it and move to the next one in 1 minute."
In the end, to consider other risks not covered in the discussion, you could also introduce a safety factor, e.g. "the time evaluated do not consider the time to put up and put down the infrastructure and the time needed to wait for residents to free up windows. For these and other possible risks we should consider an increase of 10% of the estimate."
Hello All,I did my BCG internship interview in jan and I didn't get in. Now I am preparing for full time and I am in target mba in europe. MBB are coming to the school in september. so my question is when should I start preparing? Will 4 months not be overkill?

Hi, I don’t think there’s such a thing as “too much preparation”; there is, however, such a thing as the wrong type of preparation. So 4months is not overkill if used properly. You have plenty of time between now and September, so I wouldn’t go full steam immediately. Instead think about building your preparation in a structured and consistent way. If your budget allows, I would strongly recommend starting with one coaching session early on. The goal is to: assess where you stand identify your main gaps define a clear preparation plan From there, consistency matters much more than intensity. On your concern about sounding robotic, this is usually not due to too much prep, but to the wrong kind of prep; for example, over-relying on memorized frameworks instead of learning how to lead the case and communicate in a clear, structured way. The goal is not to memorize more cases but to think better during the case. Feel free to DM me if you’d like to go deeper Best, Franco
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.
