PST Overview

In this McKinsey PST (Problem Solving Test), you are being asked to answer as many tough questions in 20 minutes as you can.

PSTs are meant to test how you approach problem solving and how well you can size up a situation. The goal isn’t necessarily to answer every single question, but to give it your best shot in the time allotted.

McKinsey PST Tips

Unlike case interviews, you can use a calculator in Problem Solving Tests. Use that to your advantage!

Pro tip: the answer key is at the end of the PST. Score yourself and see how you well you did. The target score is typically 70% or better.
