First-round MBB interviews in 10 days – how should I prioritize my preparation?

Hi there,

At this point, I would not try to increase case volume dramatically. You have already done 20–25 cases, so the priority now should be to make your performance more consistent and remove the specific weaknesses you already know you have.

I would structure the next 10 days around three things:

• Keep doing full cases, but use them diagnostically. One good case per day with a strong peer is probably more useful than doing three randomly. After every case, write down the 2–3 things that actually hurt your performance and deliberately look for those again in the next session.
• Drill exhibits separately. Your issue does not sound like reading charts; it sounds like moving from observation to implication. For every exhibit, force yourself to go through: key insight → evidence → implication for the case. If you can make that automatic, you will improve very quickly.
• Start fit now, not two days before the interview. Have 4–5 strong stories and practise them with someone who will interrupt, challenge details and ask follow-ups. The goal is not to memorise STAR answers, but to become comfortable going deeper without losing structure.

I would keep firm-specific preparation relatively light. Understand the process, know why you want each firm and speak with people there if you can, but do not change your entire case-solving approach because one interview is Bain and the other is BCG.

One thing I would also do in the final week is reduce the amount of “new” preparation. The closer you get to interview day, the more valuable consistency, confidence and clean execution become versus learning another framework or doing another ten cases.

With 10 days left, I would rather arrive having fixed two real weaknesses than having increased your case count from 25 to 40.

Hello,

I'd definitely prioritize fit, and I'd focus on finding a couple of high-quality partners to do 2–4 cases with, since that gets you closest to the real interview experience.

1. Fit: practice every day. Run through 2–3 stories every morning and evening, record yourself on video, and review your performance. You can even give the recording or transcript to an AI tool and ask for harsh feedback. For the first couple of days, that alone will give you new insights.
2. Cases: find partners with BCG and Bain experience. Ideally find one person from each firm, or a coach who has prepared candidates for these firms. Use your Master's network and ask people who interned or worked at MBB, recently or currently, to run a case with you. You can also email the firms' recruiters and ask to be connected with a consultant; firms usually agree. These partners will give you far more insightful feedback than 10 more cases with other applicants.
3. Instead of drilling exhibits separately, do full mock interviews with both a fit part and a case. Switching between the two takes focus, time goes faster than you expect, and this kind of practice significantly reduces stress, which is the main risk to a strong performance. When you do get an exhibit, lead with the "so what" first, then back it up with 1–2 numbers.

For firm-specific prep, I wouldn't go beyond case partners from each firm and one fit story that answers "Why this firm?"

Good luck!

Hi,

To me I'd fix the two weak spots first and then go back to full cases.

Starting with exhibits, I'd spend around 2 days drilling exhibits: take a chart, give yourself 60 seconds, describe what you see and say the "so what" in one sentence. 
Then spend 1 day writing and tightening your fit stories, and 1 day rehearsing them out loud. My guess is the rambling on follow-ups comes from stories that aren't structured enough yet, not from missing material.

Once you've fixed those parts, restart with cases, 1 case a day is enough if you're already performing well. At this point the quality of the debrief matters more than the number of cases.

If your budget allows, a coaching session early on is probably the best return on your time, because a coach can spot blind spots you can't see yourself and redirect your prep. I'm biased since I'm a coach, but if you do it, do it as early as possible so you still have time to act on the feedback.

You have enough time to get there. Feel free to DM me if you want me to be more specific about your situation.

All the above!

Just like a soccer team, you need to do running, dribbling, shooting drills, but you also need to scrimmage!

And, like a soccer team, you also need a good coach to tell you exactly what to work on...we can't honestly tell you what's most important for YOU as we don't know you. That said:

Make sure you're doing the right drills and the right cases with the right people though. This is very much a game of quality as much as it is quantity.

You've already told us what your weaknesses are: exhibits and FIT. So that's where I'd spend most of the next 10 days.

On exhibits, you're exactly right about your problem. You don't impress anyone by pointing out differences in numbers. You do impress however if you say the so what.

You should only ever be stating things if it helped you to answer the question/objective. At all times you should have an objective-driven approach.

So, take the #/observation, state the so what/implication, and use that to inform what happens next. Never just read every single difference on the exhibit!

On FIT, don't underestimate it! Get your 3 whys nailed down and have 3–6 flexible stories that can cover a range of questions. Then practice them out loud and have someone push you with follow-up questions. If you know you ramble, record yourself...you'll hear it immediately.

Then keep doing full cases as your “scrimmages.” I'd probably do around one good live case most days, but don't blindly chase volume. Use the full cases to test whether the exhibit drills and FIT work are actually translating.

And rest before the interview. Don't show up exhausted because you tried to cram 20 more cases into 10 days!

Given you've got two MBB interviews in 10 days, I'd take a look at my Full Interview Mastery Bundle.

Here's some reading I'd work through:

The Most Common Pitfalls in Case Interview Preparation

How to Shift Your Mindset to Ace the Case

Dos and Don'ts in a Case Interview

Candidate-Led Cases: What to Expect With Example Cases

And I'd get some variety in the cases:

Bain 1st Round: Last Mile Delivery

Bain + BCG: Hot Wheels

MBB: Climate Change Operations

I'd also listen to the Consulting Offer Blueprint to keep building your business judgment and exposure to real business problems.

Congratulations on the interviews, that is already a huge success. I would recommend to balance the preparation so you feel at ease in every situation. Additionally, I can only recommend to show your personality and stay natural (in cases too). Usually they hire for talent and not a case-robot :-) Even making a mistake is not the end if you presentation in total is excellent and naturally convincing.

Hi,

I'd focus on your weakest areas rather than doing 1-2 full cases every day.

For cases, exhibits seem to be the main gap. Do targeted chart drills and force yourself to identify the key insight and business implication within 1–2 minutes. Avoid simply describing the chart - focus on the "so what?"

For fit, I'd invest significant time here. Have polished stories for leadership, teamwork, and failure, but also strong answers to motivation questions like Why consulting? Why BCG/Bain?  Practice handling follow-up questions without rambling.

Overall, spend your time where it will have the biggest impact. Keep doing a few cases over the next 10 days to stay sharp, but prioritize exhibit drills and fit prep. Those are likely to move the needle most at this stage.

Best,

Great that you have these interviews lined up! And amazing to hear you've already been practicing and have a base. 

It would make sense to have a session with a coach to get an assessment of where you are and what is most important to change / focus on in the coming period. This will enable you to make the most of the time that you have left. 

If you don't feel comfortable with your current level of prep, the other option to consider is trying to push the interview dates. Typically, most consulting firms are flexible with this (aside from situations when they run interviews in cohorts or want to close a specialist role quickly). 

If you have any questions, don't hesitate to drop me a line. 

Best,

Hey there :)

With 10 days left, I wouldn’t just keep doing full cases. Your biggest gains are probably in exhibits and fit, since your basic structuring and maths already sound solid.

I’d do one full case most days, then spend some time drilling exhibits separately. For each chart, force yourself to state the key takeaway first, then explain the evidence behind it. For fit, get your three or four stories really tight and practice the follow up questions, especially “why?”, “what did you personally do?” and “what would you do differently?”

I’d leave the last couple of days fairly light and focus on being sharp and calm rather than trying to learn new frameworks.

Best, Alessa :)
