Thanks for making the video! FYI: on that 370x400 example, you can also just isolate the K to one side, since there are 3 zeros. So you have 37*4*K or 37*2*2*K. That way you don't have to deal with any zeros. You can do this for any calculation where all you're doing is multiplying.
These are super tips, but why is this needed in consulting when we live in a world with calculators, Excel sheets, computers, etc. I will never understand why this is tested during a consulting interview, for me it does not make sense at all, but their firms, their rules, so one must comply and show required skills...
Being able to gut check numbers is helpful for catching mistakes. If someone is presenting something to you, you probably aren't sitting there with a calculator checking every number. Being able to do the type of math in the video shows your ability to work quickly with numbers - certainly not the only skill needed to be a good consultant, but it's a useful skill to have.
@@winogradapps that's true but i will argue that as a C-Level I wont also have to check every number. as a PL either so whats the point? True, its good to have, but I have seen candidates being rejected for not having it, which is absurd imho
by far the best video on case interview math that I have seen
