When preparing for a case interview, especially under time constraints, working with an experienced coach can significantly enhance your chances of success.
💡 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.

Hey there :)
I wouldn’t worry too much. Unpaid internships can usually be verified without W2s. An offer letter, internship certificate or confirmation from HR, and a reference from your manager can all help. If they ask for additional documentation, just explain that the internships were unpaid.
Regarding the dates, I’d proactively let your recruiter know that you noticed a small mistake and provide the correct June to August dates. It’s much better to clarify this upfront than have a discrepancy come up during the background check. These things happen, and being transparent is what matters.
Good luck with the new role!
Best, Alessa :)
Ideas on how to obtain referrals for strategic consulting

Hi there,
Cold messages to random consultants rarely work because there is nothing for them to say yes to. What worked better when I was recruiting, and what I later saw from the other side on Kearney's recruiting team in Dubai, is narrowing the list and making the ask small.
Start with people who share something with you, the same university, previous employer or home country. Ask for 15 minutes on what their office looks for, not for a referral. If the call goes well, most people offer to pass your CV on themselves.
Also check each firm's careers page for events and virtual open days. Recruiters remember names from those, and that often counts as much as a referral.
If it helps, I am happy to run a free case with you. Just reach out through PrepLounge.

Any experiences of an interview at Oliver Wyman for an Engagement Management role?

Hi there,
I have not sat on an Oliver Wyman panel, so ask your recruiter for the exact rounds. What I can share is how manager-level hires were assessed from sitting on Kearney's recruiting team in Dubai, as the logic is similar across firms.
At this level the case is less about finding the answer and more about whether you can run the problem. Lay out the workplan, say what you would have each team member look at, and push toward what you would tell the client at the end of the week.
The behavioral side also carries more weight than for junior hires. Prepare stories on leading a team through a difficult phase, handling a senior client who disagreed with you, and something you sold or grew in tech. Expect them to probe your exact role in each one.
Happy to run a manager-level mock with you before the interview.

Nikola
Hi there,
I do not know CHECK24's exact process, so confirm the number of rounds with the recruiter. One thing I would prepare either way.
Inhouse strategy teams almost always case you on their own business. Before the interview, make sure you can explain how CHECK24 makes money, mainly commissions when a customer signs a contract through the portal, across insurance, energy, banking, travel and more. Know which verticals matter most and what drives growth, more users, better conversion, or higher commission per contract.
Then practice two kinds of cases. Classic ones like market sizing and profitability, and product ones like "should we launch this feature" or "why did conversion drop in car insurance". For product cases, structure around the user journey, from first visit to comparison to signed contract.
If it helps, I am happy to run a free case with you before next week. Just reach out through PrepLounge.

I would prepare for this as a business case with a digital-transformation angle, rather than as a pure strategy case or a technical IT interview.
EY Vienna’s current Technology Strategy & Transformation roles focus on topics such as digitalisation strategy, target operating models, process optimisation, digital business models and transformation roadmaps.
So I would expect questions around areas such as:
- which processes should be digitised or automated first,
- how to prioritise digital initiatives,
- how to build the business case,
- what the implementation roadmap should look like,
- and what risks could block adoption or execution.
You should still keep the usual case fundamentals sharp — structure, profitability logic, prioritisation, maths and synthesis — because the digital topic will normally sit on top of a business problem.
On language, I would be ready for both German and English. EY Vienna works with national and international clients, and current transformation roles are clearly positioned at that interface. I would still confirm the exact interview language with the recruiter.
If German is not your strongest language, practise explaining your structure, calculations and recommendation out loud in German beforehand.
If you want, feel free to reach out and I’d be happy to share how I would structure the preparation specifically for a Digital Transformation case.
Your observation is broadly right: many cases reuse the same underlying business dimensions. The problem is not using those dimensions. The problem is presenting them as a pre-built checklist rather than as a structure derived from the specific question.
1. A generic framework is not automatically bad
Market, profitability, operations, customers, competition, capabilities — these are all legitimate dimensions and they will naturally appear in many cases.
What interviewers usually dislike is when:
- the structure feels memorized,
- every case starts with the same buckets,
- the candidate cannot explain why each branch matters for this specific problem.
So the real distinction is not simply generic vs. customized. It is pre-built vs. case-specific.
2. Customization should come from the question, not from forcing a “creative” lens
You do not need to invent a completely different framework every time.
Instead, start from:
- the exact client question,
- the key drivers of that outcome,
- the most relevant dimensions for testing those drivers.
In your example, the objective is to understand why profits declined. That should be the anchor of the structure. Product, vendor, customer, timing and operations can then become useful lenses if they help explain the decline.
The important point is that the structure should have a clear logic behind it rather than simply trying to “sound customized”.
3. You should not sacrifice coverage for customization
A tailored structure does not mean committing to one narrow explanation.
You still want enough breadth to capture the main possible causes, but you should:
- prioritize the most relevant branches,
- make the sub-branches specific to the case,
- avoid adding dimensions only because they appear in a standard framework.
This is usually the best balance between coverage and specificity.
4. It is fine if the initial structure turns out to be wrong
Your first structure is only an initial hypothesis of how to solve the problem.
As the interviewer gives you new information, you should:
- update your hypotheses,
- deprioritize irrelevant branches,
- redirect the analysis where the evidence points.
Being adaptable is more important than having predicted the final answer from the start.
5. This becomes even more important at top firms
In many BCG, Bain and McKinsey cases, the problem will not fit neatly into a classic “profitability”, “market entry” or “M&A” framework.
The initial question may be more unusual and require you to think more independently about:
- what actually drives the outcome,
- what information you need,
- how to break the problem into logical components.
That is exactly why memorizing frameworks can become limiting at the more sophisticated end of case interviewing.
My recommendation would therefore be: keep the standard business dimensions in the back of your mind as a checklist, but build the visible structure from the specific question in front of you.
If you want, feel free to reach out and I’d be happy to share how I usually help candidates move from memorized frameworks to more flexible, case-specific structuring.
All the basics are there, but I still struggle to actually solve the case

Hi! I’d say driving the case is less about knowing all the techniques and more about connecting the dots.
- Always go back to the main question. Ask yourself what you’re trying to prove and how it helps solve the client’s problem.
- Focus on the “so what?” After each exhibit or calculation, explain what the findings actually mean for the business.
- Be hypothesis-driven. You don’t need to guess the right direction every time. Test your assumptions and adjust based on new information.
I’d also say PrepLounge is a great starting point for practicing this, either with a coach or with peers. Focus on full cases and getting feedback on how you move between steps, rather than just individual skills.
Hope this helps! :)
Congrats on getting to the interview round!
If you have 9 days left, try to get a sense of where you are as soon as possible. You might consider getting an expert session to know what the gap is and what it would take to close it.
Then, depending on the outcome, you could either try to push the interview or if that's not an option, double down on the feedback you received from the assessment and work on what will most improve your performance.
This would be better than you trying to do everything at once over the next week and a half.
Re cases - I wouldn't assume they will be from any specific industry, especially if you're applying for a generalist role. But do ask the recruiter. They should be able to give you more specific guidance on this.

Hi there,
Confusing situation indeed! You need to sit on this! They've said they've received your submission so you need to let them review it. You should be ok. Fingers crossed for you!
For anyone reading this who has the test coming up, my BCG Casey Simulator is an excellent resource. It includes 10 simulations, video training and detailed explanations so you can practice before the real assessment.
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.
Markt 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.
