This question is read-only because it has been merged with Tough math questions for McKinsey interview practice please?.
Hi Guys,
I am looking for a bank of drills or sets of example questions that just focus on more complex math issues. e.g. here's a set of figures how would you arrive at X, now that you have X what do you need to get Y. Any examples of cases with good quant would help too. Also, I am not preparing for an interview that is going to have particularly hard math it is just my weakest point right now so I would like to focus more heavily on it. Thanks for any feedback.
Hi Jay,
I'm a former McKinsey consultant, and I have a set of practice problems on several topcis that are more complex than mutlplcaiton or percentage calculations, like Breaekven Analysis, and maretkgin Sizing qquesitons, which are available here: The World’s #1 Selling Online Course for Quantitative Case Interview Preparation
There are a lot of other quant-focused resources on this site as well.
Enjoy,
Matthew
