How to prepare for BCG online case?

Anonymous A

Hi everybody!

I have been invited to BCG first round, which will consist of two face-to-face cases and one online case. What should I expect from the online case? Is it somehow similar to McKinsey PST/SHL? How should I prepare for it?

I will interview at the italian office in Milan, if that matters.
Thanks for your help

Hi,

There are 2 types of BCG tests:

  1. GMAT-like test with questions similar to GMAT
  2. Online Test that is based on a case and has the questions closer to PST

I have uploaded both test samples here (Online test is about airlines). I've also added BCG written case sample (Next round) and Bain written case:

As for particular recommendations for online test:

  1. Try to find as many people in your country as you can who have done the test. Ask them for the topic, industry, and questions they remember. For example in one of the countries there was a test about airlines and reading a couple of articles / company reports / wikipedia articles with industry terms could significantly improve performance
  2. Try to practice tests with strict time-management. McKinsey PST from the official web site and all mck and bcg -like tests you can find online
  3. Additional resources can be GMAT Integrated reasoning from the official guides and apps if you feel that you are not p[erforming well
  4. As far as I remember calculator is allowed on BCG test. Make sure you know how to simplify calculations and use it fast

Best!

Hi Anonymous,

the potential test is different from the McKinsey PST/SHL, although, as mentioned below, PST could still be a good practice.

For the preparation I would recommend the following:

  • Practice as much as you can on Potential test simulations. You should be able to find online the Med-Lines case, either on a PrepLounge or on Scribd (just google that). After that, Igotanoffer has several others you can purchase online
  • Once completed the BCG test simulations, move to PST practice. You can find a good number of PST test online for free. PST is different from the Potential test (the structure is not the same, in the Potential test you get penalized for wrong questions while in the McK PST you don’t, etc), but it is definitely closer to that than pure GMAT questions.
  • Do all the simulations with a time constraint. Then, after each test, report all the mistakes you did in the test. You will likely find mistakes have something in common (eg, wrong math; too much time wasted on some questions; wrong interpretation of graph; etc). Then work on these categories one by one. Many people do these simulations concentrating only on the final score and don’t spend time categorizing the type of mistakes, thus not improving their performance.

Math practice, graph interpretation and quick reading training can also be useful. You can find some more comments on that at the following link:

Finally, you have to take into account you get penalized for wrong answers in the Potential test, so you should adapt your strategy accordingly.

Best,

Francesco

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.
