Hi there,
You'll really get the best out of this exercise if you try it yourself. Why don't you post what you're thinking and we can help?
Hint: Do you think this makes more sense top-down or bottom up?
General Tips
Remember that there's rarely a "best" answer with market sizing. What's important is that you break down the problem the way it makes sense to you. Importantly, break it down so that the assumptions you make are the ones you're most comfortable in.
For example, do you know all the major brands? Great go with that. Do you understand all the segments of that country's population (either age or wealth or job breakdown)? Go with that. Do you know the total market size of a similar industry? Then break it down that way.
Some tips:
- Just like in a case, make sure you understand the question - what are you really being asked to calculate
- Decide whether a top-down or bottom-up approach is best
- Figure out what you know you know, and what you know you don't know, but could estimate
- This helps you determine how to split out buckets
- Stay flexible - you can start with a "high-level" market sizing, but gauge your interviewers reaction....if it looks like they want you to do more...then go along level deeper in terms of your splits
