Hi, do I need to study market sizing type of case for Capital One Case Study Interviews for Business Manager positions?

Hi There,

From what I read it seems like there is not necessarily a standard case or case type, so it would not hurt at least feeling comfortable going through a market type case. However, I would make sure you feel comfortable with casing overall as well!

Hope this helps!

Hi there,

Yes, it’s a good idea to practice market sizing for Capital One’s Business Manager case interviews. While the cases are often data-heavy and focused on business judgment, market sizing questions do come up — especially as part of broader profitability or growth strategy problems.

They may ask you to estimate things like:

• The size of a potential credit card market
• How many customers might adopt a new product
• Revenue impact of launching a feature

You don’t need to master every niche format, but being comfortable with structured estimation, clear assumptions, and quick math will definitely help.

Happy to help you prep – feel free to reach out.

Hi there, 

Usually market sizing is not accessed as an individual case type, rather, it is more commonly to be embedded in a case, as part of the quant assessment. 

Therefore, no harm to get familiar / comfortable with the market sizing approaches, just in case you encounter one during the case.

Hi there, 

I would go back to the recruiter and ask them about the format of the interview and what 'type' of cases they use. This will help you have a more tailored prep journey.

But by and large, yes, I would prepare market sizing questions. They are the bread and butter of almost any consulting interview, so it makes sense to be covered on this side.

Hi there,

I would be happy to share my thoughts on your question:

• Please keep in mind that except for Bain in the UK and few smaller consulting firms, most consulting firms have not used standalone market size estimations for a long time. While this does not mean it never happens, this type of case study question is typically not be very meaningful for both the candidate and interviewer, as only a few skills are being tested.

Hi,

It is better for you to play on the safe side and study it, the logic is actually pretty simple.

Crafting Cases has a 7 days free course and one of the modules is market sizing. May be worth looking.
