1. Firstly, understand the test

A. Why does PST come to exist?

The normal recruitment process typically involves two processes: CV screening and Interview. CV screening proves efficient in sorting potential candidates with low-usage of resources, however does not 100% correctly assess the candidates’ ability. In the case of an interview, it is time-consuming to devote to interviewing all who pass CV screening.

Therefore, it happens to be a gap between two processes. That is why McKinsey creates Problem Solving Test.


B. What is PST like?

It has 26 multiple choice questions, divided into 3 cases with time limitation of 60 minutes

Often the test includes 6 types of questions:

Which of the following values is the best estimate of ABC’s revenue in Year 4?

Which of the following is TRUE based on the data presented in Exhibit 2?

Which of the following reasons, if TRUE, would best explain the increasing trend in X, Y, and Z?
