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.

Hey! Totally relatable struggle, and the good news is that McKinsey case math isn't actually hard math. It's basic arithmetic done quickly under pressure, which is a very different skill. At the same time, math fluency is close to a precondition for getting through an MBB interview. You can have a brilliant structure and great communication, but if you stall on a 15% of 4B calculation, the interviewer notices. The bar isn't genius level. It's fast and confident on basics. Here are the 4 main things to drill for McKinsey math. I tell my coachees that if they master these, then 90% of case calculations become trivial: 1. Percentages via the anchor method. Memorize only 5 anchors (1%, 5%, 10%, 25%, 50%) and derive everything else by adding or multiplying them These anchors are very easy to find: e.g., 10% of X is 0.X 15% = 10% + 5%. 16% = 10% + 5% + 1%. 12.5% = half of 25% Also drill the reverse: "240 is 15% of what?" becomes 240 ÷ 15 × 100 = 1,600. This shows up constantly in profitability and market share questions. 2. Percent increase and decrease. This is where most candidates lose points, because the traps are conceptual, not arithmetic. Growth, margin changes, and price/volume questions all live here. Three things to internalize: +20% then minus 20% does not return you to the start (you end at 96, not 100) Chained percentages multiply, they don't add, so two consecutive +10% growth years are +21%, not +20%; Reverse problems like "after a 25% discount, the price is 450, what was the original?" become 450 ÷ 0.75 = 600 (not 450 + 25%). 3. The four operations with shortcuts. Stop doing long multiplication, a few examples: Round and correct for addition/subtraction (487 + 326 becomes 500 + 326 minus 13). Use the "fraction of 100" trick for multiplications by 25, 50, 75, 12.5 (48 × 75 = 48 × 3 ÷ 4 × 100 = 3,600). Decompose for awkward multiplications (17 × 14 = 17 × 10 plus 17 × 4 = 238). Halve three times for divisions by 8. 4. k/M/B notation, treating suffixes like exponents. Never write zeros in a case. Handle the number and the suffix separately: 50M × 200 becomes (50 × 200) M = 10,000M = 10B. Memorize the rules: k × k = M, k × M = B, B ÷ M = k. Combine with percentages for market sizing: 15% of 4B = 0.6B = 600M. How to actually practice 10 minutes a day, timed, max 10 seconds per calculation, written by hand. Consistency beats long sessions. Drill one of the 4 areas per session rather than mixing, because you build pattern recognition faster that way. Once individual drills feel easy, simulate the real cognitive load: do mental math while pacing the room, or while explaining your structure out loud. That's the actual interview condition. One last thing on public maths (i.e., maths in front of someone else) When you freeze in the moment, it's almost always because you didn't set up the calculation before starting it. Take 5 seconds to say out loud, "OK, I need to find X, which equals Y times Z." Interviewers love this because it shows structure and it gives your brain a clear path. Diving into numbers without setup is what causes the blank. For you and for everyone else: DM me if you want a PDF document with some drills! Best, Tom
Given my experience so far, am I competitive for Big 4 consulting internships or aiming too high?

Short answer: yes, you are competitive; you’re not aiming too high. You already have a solid profile (UT Austin, ~3.65 GPA, early consulting exposure, leadership, relevant internships) and Big 4 consulting internships are realistic from where you stand. That said, you’re not a lock yet so you should apply broadly across Big 4 and boutiques. The main areas of improvement in my opinion are: Consulting signal still a bit light; student consulting orgs, case competitions, nonprofit projects would strengthen your story Brand name exposure is limited; not a dealbreaker, but it increases the importance of networking GPA is solid but not standout; you’ll need to differentiate through impact and narrative From a practical standpoint I would recommend you to: Build a clear “why consulting” story Network consistently with UT Austin alumni in consulting Start case interview prep early as performance there is decisive Best, Franco
Does a referral matter for screening at BCG London?

A referral does matter quite a lot (even though it’s not a golden ticket), and that is true for any consulting company, anywhere. In practice, it helps your CV get attention and be looked at more carefully. Also, not all referrals are equal. A strong, credible referral (someone who knows you and can vouch for you) carries much more weight than a generic one. If you want, feel free to DM me to discuss smart ways to secure referrals, happy to discuss. Regards, Franco
I wouldn’t over-index on “case difficulty” labels. I’ve done hiundreds of interviews in my life, and I've personally used identical cases for undergrads, MBAs, and even experienced hires. What changes is the bar, not the case. For a junior candidate, I’ll be more forgiving on structure or math, for an MBA, I’ll expect sharper insights and cleaner delivery. So mapping CaseCoach easy/medium/hard to McKinsey isn’t very meaningful. A “hard” case doesn’t mean a tougher interview, it can actually come with a slightly lower bar, while an “easy” case might require near-perfect execution. Bottom line: cases are cases, your performance is what’s being tested, not the label on the problem. Regards, Franco
Q.1) Is there a cooling period at Bain Capability Network & Mckinsey if I get rejected at the resume screening Stage but I never received a formal rejection email. Should I continue applying for other CoE's ?

Q1, typical cooling period of around 12 to 18 months after a formal rejection, but if you never received a formal rejection email it is a grey area. Could be that system has logged you as rejected for that specific role even without the email. You can still apply to other CoEs but potentially use a different office or capability area to avoid getting auto-screened out. Worth reaching out to a recruiter directly to clarify. Q2, a few possible reasons. Potentially posting could have been pulled or paused without being taken off the public site. It could also be a role being filled through a specific recruiter pipeline rather than open referrals. Best to ask your contacts to check directly with the recruiting team or the hiring manager if they know them. Good luck !
Good question — for MBB in Riyadh, the logic is actually quite straightforward. They don’t recruit from “Riyadh-specific MBAs.” They recruit from top global MBA programs, and then you target the Middle East office. The main feeders are: INSEAD → probably the strongest pipeline into Middle East (very large class, historically strong presence in the region) London Business School → very strong for both UAE and KSA IESE Business School → also places well into the region Then top US schools: Harvard Business School Stanford Graduate School of Business Wharton School These also work very well, though the path to the Middle East may require a bit more intentional networking. A couple of practical points: INSEAD is often the most direct route for Middle East MBB (scale + proximity + alumni network) LBS and IESE are also very strong and often slightly more flexible geographically US MBAs are top-tier but less “default” for KSA — still very possible What really matters is: getting into a top program performing well there networking early with the Middle East offices being clear on your motivation for the region There’s no “secret MBA” for Riyadh — it’s more about how you use the platform. If you want, happy to talk through which one makes most sense based on your profile.
Hey,There is a lot of uncertainty in the MENA region due to the current geopolitical scenario. When this happens, long-term projects are typically halted or postponed, and short-term engagements (e.g., due diligences) are also limited—there is simply too much uncertainty right now to buy a new company or start a joint venture.Thus, this slowdown is unfortunately normal.I wouldn't stress about it too much: In a month or so, consulting firms and companies will likely have a clearer understanding of whether this is the new normal, or if the situation in Iran has evolved. A lot of expats are planning to leave the area and are recruiting for opportunities abroad (I can say this confidently because I am coaching a few people doing exactly this). This means competition might slow down and turnover could increase, resulting in more opportunities for new joiners Long-term, unless we enter a multi-year conflict around Hormuz, I don't think the prospects for MENA consulting (or the overall hiring numbers) will change much.Hope this helps,Tom
Could a 9-month gap on my CV deprioritize my profile for recruiters?

Hi, A 9-month gap can raise questions, so it should be framed clearly and then moved on. Recruiters mainly react to unexplained gaps, not the gap itself. On the CV, I’d make it explicit and neutral: something like “GMAT & consulting interview preparation” if you cannot justify it otherwise. That already signals intent and direction. If you have anything tangible (score, cases practiced, courses), even better; keep it factual, no over-explaining. Then use the cover letter to address it in one clean line, not defensively: you took time to prepare, the market slowed due to external factors, and now you’re fully focused on recruiting. If you want, feel free to share your resume. I’m happy to give you direct feedback. Regards, 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.
