Hi everyone,

I'm new to tackling case studies, and I am job searching (I've been in corporate finance for almost a year now, doing a lot of reporting, and have accounting background. I would like to break into strategic finance or do some sort of lateral move where there is opportunity to grow) in an extremely competitive market, but I'm struggling a lot with the technical case interviews where I'm given no feedback b/c of company policy. However, I would like to get some feedback so I know how to improve for future rounds:

Here are few sample questions (candidates are free to ask clarifying questions). It is themed around market product launch

  1. Pretend that X company is entering new market, please provide market size & 1st year sale in unit or revenue for Y home product

Answer: I'm going to assume that there is 5 million people in this market, and that 2 million of the existing population have no interest in the Y home product, which leaves us with 3 million potential new customer. Furthermore, I'm going to assume each household as 3 people. 3million/3=1 million products that could be sold. I'm also going to assume this new Y home product costs $200 per unit. 1 million x $200 = $200 million.

Market size: 1 million, 1st year sales: $200 million

2) Continuing off the 1st question, assume it's been a year since we sold our Y product, what other products from our company would influence our success?

Answer: I'm going to assume that there are other home products that work well with the Y product, so I would say those that pair with the Y product would influence the success.

3) If you could have access to any information, what else would you like to know?

Answer: competitive landscape because I'm curious about market share for this particular product b) product capabilities: what makes our product advantageous/better than others c) barrier to entry d) logistics: value supply chain - how are we building this product and where e) customer demand - do our customers in Germany want it?

4) How would you measure success in marketing campaign, and how do you determine if the metrics drove the marketing activity? (I acknowledge that I struggled with this question because I did not expect the interviewer to ask me how we will use the metrics to measure whether or not it drove a marketing activity, but I am open to feedback).

Answer: ROI, CLV, CAC

ROI: If marketing spend went up, but ROI also went up, I'd assume that marketing was involved

CAC: If we see this go up, in addition to % increase to ROI, I'd say the marketing activity drove an increase to ROI

Thanks in advance!!

Hello there, 


Being in the early stage of the whole process allows you yet to prepare, no worry about that. I would, however, try to start with the following before jumping solving the cases: 


1. Understand well MBB's recruiting process, where you can fit
2. Evaluate your skills and strengths vs. what is required to understand where the gaps are and plan how to close them most effectively
3. Spend enough time on your CV and cover letter (step where 90% of candidates are out …. don't underestimate this step)
4. Practice for your interviews (fit and case)


The most common mistakes candidate do:
- don't understand the recruiting process, what is important, and where to dedicate time/resources → they kill their chances at the beginning
- Overestimate the role of the business case and underestimate the CV, cover letter and fit interview preparation → without this you won't get the opportunity to do the business case
- Trying to follow a business case process without fully understanding it… no chance to correctly apply it (e.g. what exactly is framework, hypothesis, etc.)
- Aiming to match the case solution of someone else, limiting their thinking and ability to follow their judgment… while one of the key strengths we look for at MBB is your ability to be creative and think out of the box


It is not easy to get in… actually t is easier to get into Harvard than into MBB.... you can approach it by relying on the luck that comes to you or you create the luck (likely the 1% of candidates that gets in probably took this step)!

If you would like to chat deeper, please feel free to reach out,

Wishing you all the best,
Lucie

PS: whatever option you choose:  An investment in knowledge pays the best interest.

Hey there,

First of all, I’m not sure I understand where you are in your search: have you already identified companies you want to work for? Have you already applied? Do you have interviews lined up? Based on your question, it seems you have had an interview already but without feedback. Does it mean you passed?

 

Regarding the case preparation, I have the impression you haven’t practice extensively with a partner. Do you know someone also applying? Have you already used online free resources to practice? A coach should be able to help you structure your training, give your personalized advices and make sure you feel prepared during the interview.

 

In terms of feedback for the example you gave: 

- It seems like you are making many assumptions without challenging them with the interviewer. What type of product is Y? Is it a one-time long-term purchase per household? Is it a monthly purchase per individual? Market sizing will not look the same for toilet paper vs. home appliances.
- regarding the other info you’d like to know, it lacks intent. Start with what you’re trying to estimate: additional top line potential? Improved bottom line? Then explain what information would help you estimate this and reach the management objective set for product Y. 
- the latest question seems a bit like a curve ball to me. Except if you’re applying for a position specific to marketing or if you have a marketing background, I wouldn’t expect a candidate to know about marketing effectiveness KPI. So probably it’s just to test your thinking in new situations.
 

Again, I don’t know exactly where you stand in the process, but based on your answers I would highly recommend you get coached before your next interview.

Hi Axel, Thanks for your comment! I failed this interview (one of FAANG) companies, which is why I'm hoping to seek advice/feedback, so I can improve for future rounds that do come up, and you're right - I do need a practice partner because I was doing a lot of case studies on my own (and I'm still relatively new). I talked to as many as people possible before the interview, and the employees couldn't really tell me what questions may come up b/c it was variable between the hiring managers. However, I'll consider hiring a coach given my interview round was quite disastrous...I appreciate your feedback again:)

Hi there,

What you're really looking for is free coaching here.

The short answer in terms of feedback is that you have good instincts but your answers are still too narrow/limiting. For example, in the 1st one, you need to do a full market sizing.

Feel free to take a look at coaching profiles and pick a coach that suits you best. The Prep4Success program is a good option if you want to shop a bit cheaper (but higher variability in coach quality).

Alternatively, the “free” option is coaching with other candidates here. Of course, there's a blind leading the blind aspect here you need to be careful about!
