Estimation questions - How many personal trainers are there in London?

Hi there,

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

• First of all, can you please provide a proposal that I can review?
• Moreover, please keep in mind that most major strategy 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 may not be very meaningful for both the candidate and interviewer, as only a few skills are being tested.
• That being said, simpler market size estimations may still be a part of a case study, for instance when estimating the revenues of the client company is required.

If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.

Best,

Hagen
