Tough math questions for McKinsey interview practice please?

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

Hello Jay,

aside from Guennael's recommendation, you should also feel free to make use of PrepLounge's "mental math tool": https://www.preplounge.com/en/mental-math.php

Good luck!

Best wishes,

Ashkan

Not exactly what you are looking for, but i suggest you spend 15-20 minutes a day on caseinterviewmath.com for rapid-fire practice. It will rank you by speed and accuracy as well, i used it to grest effect when i was in your shoes, and a number of my clients have made good progress as well.

Also - preplounge has some very good material. And no, they do not pay me to tell you that :)

I recommend you try GMAT math questions. One type of GMAT math questions is called word problem, which resembles math question (slightly harder in my opinion) you get at case interview.

Doing some GMAT math questions will boost your confidence.
