Hello, I'm stuck on a few market sizing questions and would really appreciate advice on how to structure the questions. How many truck drivers are in the US? How many airplanes are currently flying across the US?

Hey; I honestly think that both Case in Point and Case Interview Secrets have great sections on Market Sizing that focus on the same principle of creating assumptions and a general formula. Truck Drivers in US: Assumed Population = 320m people Age Distribution = Linear Life Expectancy= 80 years Truck Driving Labour Force Size = 21-60 (or 50% of population) Lower Income Families = 20% Middle Income Families = 50% Higher Income Families = 30% Assumed Truck Drivers are 10% of Lower and Middle Income Families 320m * 50% * 70% * 10% = 11.2m people As for the second question, I'll reuse some

“I spoke with Michael who works in Equity Research, we talked about some career paths that I can take and why Asset Management is a good fit. During our talk, we went over my CV and were able to pick out some points that were relevant to AM. We then discussed my next steps if I wanted to pursue AM, going over what firms to target and what level to reach. When discussing the level to reach, Michael went over 2 areas where I can build on and focus my attention to help me stand out when I apply to some of the AM firms we talked about. He mentioned why and how they are relevant along with what to start with. Michael was extremely reassuring and kind throughout our talk and I was happy that he reached out to me on Slack when I put my first introductory message in the general page. We need our talk with potentially meeting again to do a mock stock pitch or just to catch up on my progression.”

Management Consulting 7 Stories Review

“Third session with Matt and he is a really great mentor! This session was especially helpful, and I was able to significantly improve my seven behavioral interview stories in a short amount of time. I really appreciated his industry expertise and the many actionable takeaways he provided. He was also incredibly kind, attentive, and easy to talk to, taking the time to listen to my thoughts and provide thoughtful feedback. Scheduling was very flexible and straightforward, which I also appreciated. He even offered to conduct another mock interview with me later, which was extremely generous. Overall, a fantastic mentor, and I would definitely book another session with him!”
