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, I would say it is a bit uncommon from my experience to get such a delay in getting a reply, especially given that as an experienced hire you would not be part of the structured recruiting process. That being said, not unheard of and I don't think it is any indication of the interview outcome. At this point I would try to wait another week, since you've already done a follow-up, and if still no reply until then you could send another email to the recruiter. The waiting period is really hard ... Hang on in there and hoping for a positive answer for you! Ariadna
Hi, First of all, good luck with your interviews, exciting stage to be at. I’ve interviewed quite a bit in SEA as a BCG Principal,so I’m familiar with how things typically work there ;-) Usually the first round consists of two interviews, but its not a strict rule. If they didn’t mention a second interview as part of Round 1, it’s quite possible that what you had was the full first round. In terms of timing decisions are often made quite quickly. However, for more specialized roles (e.g. with specific industry or functional expertise) it can take a bit longer, sometimes up to a couple of weeks, as they may be coordinating across multiple candidates to fill a limited number of targeted roles. This is a bit different from generalist hiring If you pass the first round, you will move on to a second round with most likely two interviews with MDs or Senior MDs from your practice area. If you want to discuss further (e.g., how second rounds differ or how to prepare), feel free to DM me Best of luck! Franco
Hi, I’m sorry to hear about the rejection Keep going, it’s not the end of the world, and it’s definitely not a final no. You can always reapply in a couple of years, or explore other firms that are just as strong. On your question: LinkedIn plays a rolebut it’s a very minor one, so I wouldn’t overemphasize it. Recruiting teams might cross-check your CV with your LinkedIn profile, but as long as everything is consistent, that’s pretty much it You’re not expected to build a personal brand or have an “influencer-style”. There acould be many other reasons why you might not have been invited, like: Lack of clear top performer signals (e.g. top grades, awards, fast progression, ... Not enough leadership or impact shown School or experience not strongly targeted ..or simply high competition WHat I'd suggest you in terms of next steps is: Apply to other MBB firms if you haven’t already Also consider strong Tier 2 firms; they’re typically more accessible; Build more experience there and then reapply to MBB with a stronger profile Happy to take a look at your CV or chat further if useful, just DM me. Best, Franco
How to structure broad cases asking for root causes and improvement levers at the same time?

This is actually a very common type of case and your instinct is directionally right. the main issue is that your structure became too deep and complex to communicate effectively My first point: going to a 4th layer is usually overkill. In an interview setting that level of detail is hard to deliver clearly without losing the interviewer. In most cases,a solid 2-layer structure plus a 3rd layer of supporting hypotheses is more than enough Coming to your questions: 1) Integrating root causes and improvement levers You have two clean options: Category-based approach (classic): Structure by revenues (price, volume, mix) and costs (fixed vs variable) For each bucket explain that you will first diagnose what is happening, and then identify improvement actions based on the findings. This keeps diagnosis and solutions logically linked without overcomplicating the structure Process-based approach (often easier to communicate): Diagnose the current situation (revenues and costs) Identify improvement levers (based on the diagnosis) Define an implementation roadmap (prioritization, impact vs effort) Assess risks and required capabilities This second approach is often more intuitive especially in broad cases like this one, becaus it mirrors how a real project would be executed. 2) How exhaustive should you be? Levels 3 and 4 (which, again, I would compress into one hypothesis layer) should not be fully MECE. If you try to be exhaustive there, your structure will become unmanageable and hardto communicate. Instead: Keep levels 1 and 2 MECE Use level 3 for a few high-probability, well-chosen hypotheses Think of hypotheses as examples you want to test not an exhaustive list The goal of the framework is to simplify complexity, not to show that you can list every possible issue. A common trap is trying to “boil the ocean”; strong candidates prioritize and focus on the most likely drivers rather than covering everything.

First of all, congrats on the offer!!! If I understood correctly, you’re still a student and will remain at university until your start date, so technically there isn’t really a “gap year” Am I getting that right? If so, you’re already in a good spot and there’sno red flag here If instead I misunderstood and you do have a real gap to fill, I wouldn’t overthink it The best use of that time is to pick one or two meaningful things and do them well: Relevant work experience (preferred): startups, scale-ups, corporate strategy, VC, product roles; anything problem-solving heavy but not direct competitors (respect your clause Internships or part-time roles during university if timing allows Exchange / thesis / strong academic performance if you’re still studying Something distinctive: entrepreneurship, NGO work, or a personal project with clear impact.. Optional: light skill-building (Excel, basic coding, finance), but don’t over-invest in courses At the end of the day, what really matters is the story: you want to show that you used that time to build problem-solving skills, take ownership, and create some form of impact. Hope this helps, Best, Franco
Are you going to get new McKinsey solve invite for every application?

You typically won’t get a new Solve invite for every application McKinsey usually reuses your Solve score for a certain period of time (often around 12 months, though it can vary by region and role). So if you’ve already completed it for the NGWL event they will most likely use that same result when you apply to a full-time role. Only in some cases (e.g., expired score, different recruiting track, ... you might be asked to retake it. Hope it helps, Franco
Tell me about yourself/walk me through your resume - round 2 same interviewer

Hi there, For a second round with the same interviewer, you don’t want to repeat everything word-for-word from the first round — that can feel stale. At the same time, you need consistency: your story should match what you said before. Here’s a practical approach: Brief recap, not full repeat – Start with 1–2 sentences summarizing who you are professionally (e.g., your background, key experience). Highlight new angles – Focus on aspects you didn’t emphasize the first time or that are especially relevant to this round. For example, a particular achievement, skill, or motivation that ties into the role. Connect to the role – End by explaining why this background makes you a strong fit for the current role or the next step in the process. Think of it like giving an updated “highlight reel” rather than replaying the entire first round. Keep it concise, smooth, and confident. Good luck!
Hey! Hope all is well First of all, congratulations on getting back to the interview stage — that's no small achievement, you should feel great about it! Your situation is not uncommon at all. In fact, a much younger version of myself was once there :) I do not think they will generally ask about this much (i.e., this is not a topic they will stress on for a lot of the behavioral portion of the interview). But if they do, I would stick to your first two points On point #1: I'd focus more on rectifying actions, rather than highlighting the gaps. So be brief on the gaps, and double down on your experience in casing with MBB consultants (even mentioning some names that the interviewer would know may help soften the interview!) Point #2: Aligned on that On point #3 — I'd leave it out. Sometimes less is more :) Bust most importantly, don't overthink it. The fact that they've invited you back means they already see something in you. Go in confident, trust your prep, and go make the most out of it! Feel free to DM me if you have any questions Best of luck! Karim
Hello! Hope you're doing well! Great to see you've started your journey; brings back memories :) First and foremost, and this is something I always tell to those starting off: this journey is long, and it is hard Some people nail it quickly, but for most, myself included, it took real time to scale up. So before anything else, manage your expectations. Give yourself permission for this to take the time it takes That said, you've clearly taken the right first steps. The structured approach, the honest self-diagnosis, the coaching sessions; good on you for that On timelines for each gap, my honest take is that nobody can give you one, because it's person-specific. For example, comms took me far longer than I ever expected to fix. Someone else might flip that entirely. Trying to map your progress empirically may mess with your expectations What I can say is that two months is a great timeline, with the right schedule and the right people But, the routine and who you case with are really crucial for progress. The routine builds the case "muscle", but who you train that muscle with consistently is equally as importnat; you need to ensure that you have built a pipeline of individuals that you are casing with that can give you actionable feedback to help you (i.e., think friends and colleagues from your network that are already in the industry, that can case you every now and then - build a pipeline with those if you can to supplement your peer cases) Let me know if you have any questions, happy to catch up over a quick chat! Best, Karim P.S. It does not hurt to start networking now and introducing yourself to representatives in the companies you want. This will take time anyways so might as well get started in parallel. My two cents :)
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.
