Angie I have to say thank you to you. Because of your useful video, I pass the job interview of one of the Big Four accountant firms by your logic framework in the campus recruitment. Love you so much and hope everything is well with you😃😃

[FotopoulosDimitris]

Angie this is the second video of yours that I'm watching, and I already know that I'll be watching all of them in my preparation for my interview. It is my first ever real corporate interview and I hope it goes really well. At least I'm Planing on it.
Love from Greece

Love the creativity and editing skills (and efforts!) you put into your videos ❤️ After the fun intro, I had hoped to see your alter egos in the outro again 😇

Recently discovered your channel and honestly, you’re a genius! I really enjoy how clear and creative you’re videos are. Maybe it’s also because you’re a fellow consulting girlie and I don’t see a lot of females make consulting content.

[AknEvns]

Amazing video! Thank you so much for those precious information.

Great video Miss Angie Lu, needed to estimate my TAM. Thanks!

[mariaeduardafranco]

Angie, thank you for this video and all the content you share here! It’s been pretty helpful for my prep.

Hey, thanks for the great video! I think the distribution plot you used is normal distribution btw! Equal distribution should be a flat line.

[astridbaye]

Would it make a difference to further down size the resident population by mentioning that a lot of people are very health conscious now and avoid pastries, so the aging population from say 50-70 could consume way less?

[alizey]

Hi! I have a question, if we use the probability curve then shouldn't the population of people who eat croissants be 95% of the total population?

[anishasuri]

Hi, thank you for such an informative video. I have one question: In a case interview, can we ask the interviewer questions like the population of Paris or other general questions that help us frame a base for the hypothesis?

[monayzc]

Thank you for such a helpful video! I was wondering, is data such as Paris population accessible during the interview, or do we have to estimate/memorize that?

[dorukbayraktar]

Tourist calculation is wrong, because you assume that each tourist stays one day on average in Paris. You need to multiply the yearly number of tourists by the average number of days stayed in paris, then divide the product by 365 to find the number of tourists in paris on a given day

[carolinacoutinho]

Great tips! But we should consider also the number of days in avg that tourists spend in Paris, because when you dive per 360 you are considering that each tourist just stays one day in the city.

[inezjames]

Hi Angie, I think your video offers the clearest and most structured explanation on approaching market sizing questions! A quick question though - does it make sense if I assume Parisian residents enjoy 1 croissant per day, say for breakfast; while for tourists, they may have 2 per day, say both for breakfast and afternoon snacks? Great thanks for the work!!!

[paulineottavj]

If we have no idea about the beginning hypothesis (eg population of a given city), will this number be provided to us?

[McofCOD]

Something that I always like to point out when I see it is that you mentioned the population of Paris as 2M. Using the metropolitan area is a more accurate measurement of city population because it includes the people that live in the residential suburbs around the central city districts. This difference can be particularly pervasive when there is a lot of urban sprawl. The Paris metro region is roughly 11-12M last time I checked, and assuming a large number of those people conduct their daily business within the city, you’re probably looking at some quite drastic changes to your underlying numbers.

[mominakazim]

How did we determine that the addressable population of local residents in Paris is 75%?

[Negrurismo]

I have a question. Isn't this based on the wrong assumption that tourists will only spend one day in the city? Or do you estimate that even if it doubles or x7 it wont be meaningful compared to the residents?

[insights_isha]

How can we calculate the number of tourists in a city? Please share your thoughts and approach
