On market sizing cases, I was told to improve my structuring. Also, all my assumptions were questioned repeatedly, and after getting flustered I did not pass the interview.
I have had two Big 4 interviews (first stage) now, and they all had market estimation cases. How can I improve on this?

Hi,
It's less about different types of the problems but rather about the tools that you use:
1) First of all, there are 2 ways to structure market sizing:
2) You should learn the key market sizing techniques:
3) You should learn the key tools:
4) Learn key numbers: populations, gas price, gas consumption, Boeing speed and nmber of seats, average salary, # of gates in the airport, GDP growth rate, inflation, etc.
5) Practice 10-15 cases and you'll be fine. Almost all casebooks have good market sizing examples and the solutions
Feel free to PM for clarifications
Good Luck!

Hi,
From what you said, I see some issues might come from:
1. Your structure wasn't organized enough to allow each variable bucket (with an assumption behind it) to be constantly changed as the interviewer questions your assumptions
2. Your main variable was not mathematically broken down in the right way (at one or more branches of your issue tree)
3. You did not have enough depth when breaking down your main variable (not enough levels in your issue tree), so the interviewer expected more detail in your assumptions
4. Or, your communication of the structure was not clear enough and, even if you did alright on paper, you were perceived as unstructured to the interviewer
Remember: market sizing / estimation questions are not about getting the right number. It's about having the right process, reasonable assumptions, sharp math and assuring your results make sense.
Please, feel free to reach out if you have any other questions

Hi, I recommend building issue trees starting from the resolution formula of the market sizing. I have a specific package to crack it, feel free to text me to understand if I can help.

Hello, can you give more detail to "improve your structuring"? This is too generic to give insightful information. Feel free to PM it to me.
Cheers!
