I was lucky enough to make it past McKinsey's resume screen for a summer business analyst position and now I have to take an online assessment. It doesn't seem like the typical PST because it is made up of a 45 minute verbal reasoning test and a 45 minute numerical test. It is all online and even allows a calculator. I am not sure if it is worth studying the PST material on the McKinsey website or if I should just stick with the practice test link they sent me on the SHL site. Does anyone have any experience with this? How should I prepare?
