Hi there, I have been recently asked a market sizing question during an IB interview. I am not really into consulting preparation, but it seems interviews for both sectors are increasingly similar so...here I am, trying to practice my Market Sizing skills (whatever it takes).
The question, which got me clearly unprepared, was as follows:
"Please calculate how many cars go through X street in Madrid between 8 am and 9 am"
Yes, that´s all. It may seem so easy for those of you with a solid background in case interviews, but this one got me rejected from one of the biggest Investment Banks in Europe.
So, given my obviously-non-existing problem-solving abilities, I need to ask for help (I just cannot find a convincing way of structuring this question, even though I am practicing other market sizings that seem much more easy to me).
I would be more than grateful to anyone willing to give me any tip about this one, since I have not identified any similar market sizing (probably due to my lack of preparation).
Again, thank you!!! any comment is more than welcome
"a car travels at a slow speed of 10km/h, it will take a car 10mins to do 1km" - are you sure about this number?
Thank you so much Mr.Anonymous A, thank you for taking the time to answer (you really helped me) Had good references about this website, have just confirmed. I have seen here that a tree structure should also be used when facing any market sizing question, do you agree? It may be difficult to fit in some cases I guess...Again, thank you;)
It might make sense to also consider that not all cars will travel the whole length of the street and might go left or right into other streets or park somewhere. hence, it might make sense to assume an average length travelled per car on the street and the average distance to arrive at a car turnover rate per hour.
