Experience with McKinsey PST round?

Anonymous A asked on Oct 22, 2017 - 4 answers

Hello PL community! Reaching out to ask for advice and experience/s with Mckinsey's PST? I have asked several peers about their experiences and how good/bad they felt after taking it and have received varied feedback!

Looking to hear about experiences, and what was the best way you prepared for it!

Please and thank you!

I just took and passed the PST test.

I noticed the following things:

  • I did a lot of preparation. I worked through the McK practice tests a couple of times. I did some of the external tests provided by a few websites (they were on a different level most of the times - best preparation was the McK tests). Total maybe took 10 practice tests (2 times the 3 original ones, and whatever I could find).
  • Once you know the type of quetions they are asking, it is pretty straightforward.
  • I found a lot of people that showed up on the day were less prepared: They had only done 1 test, heard about the test a week before, thought it would be a 'either you have it or not' situation.

Therefore, my personal view is that the PST is a really good way for McKinsey to weed out applications that just apply for fun and games, and don't really want to put effort in. Those people may be capable to do the job, but doing the test without preparation is hard (I had to let go of some GMAT logic as I was just answering a wrong question...).

If you prepare with the materials available and speed up your maths, you should be good.

I suggest the following:

Do one full case from the mck website in 60 min. Check your score. Target score is 22 out of 26 correct. If you do 17-18 correct you have great chances to improve it quite fast. If lower - it will take couple of months

If your score is high:

  • Buy Viktor Cheng test prep program - best materials I've seen so far. Works also for express prep.
  • Practice your math. Check exercises on Cheng website. Key things - multiplication of 2 digit numbers, operations with zeros and division (Learn division table, ie. 1/8 = 12.5%, 8/9 = 88%, Learn up to 8/9)
  • Do the 2nd test and check the score

If your score is low you need fundamental prep:

  • GMAT IR, quant and verbal parts
  • PST-like tests available online

I also practiced a lot with GMAT preparation books, and it worked!

Which companies are currently using written tests ?

All major firms like McKinsey, BCG and Bain use tests to assess a candidate's analytical skills. However the design of those tests can differ a lot.
