Thanks a lot for your outstanding advice and guidance. I am an APD candidate aspiring to work at McKinsey.
Although I find lots of resources on case interviews, I could not find enough resources (except from what is available through McKinsey's website) on the McKinsey Problem Solving Test (PST), that McKinsey is handing out these days in their first round interviews.
Can you please suggest or direct to some resource on that area? Your help will be much appreciated.
I just finished entirely re-writing my resource page on the McKinsey Problem Solving Test.
It includes math practice resources and links to several sample tests / similar tests.
