McKinsey Imbellus Game

Quantitative tests like the McKinsey Problem Solving Test, McKinsey Online Problem Solving Test (also known as McKinsey Digital Assessment or the McKinsey Imbellus Game) and the BCG Potential test are used because there is a certain set of numerical computation and logical thinking skills required to be successful in consulting and these tests are used to evaluate these types of skills.

How to Prepare for a Quantitative Test

It is important to remember that while the format of the McKinsey Online Problem Test, BCG Potential test and other quantitative tests from other firms maybe different the skills or problem solving ability being tested is the same so the preparation process can be the same regardless of which test you are taking.

The main areas to practice are computations and data interpretation.

Practice Computations

The first area to practice is the speed and accuracy of your arithmetic as these tests are timed tests.

Math computation skills are a muscle so the more you use it the stronger it gets so practice, practice, practice. Work through as many quantitative problems as you can while you prepare for your test.

Practice Data Interpretation

The other area you will want to practice and develop is your data interpretation skills.

Polishing your foundational skills in word problems and data interpretation is where you should focus your attention.

The questions on these quantitative tests most closely resemble practice test questions from certain sections of the GRE particularly word problems and data interpretation questions so these are good resources to use in your preparation.

Recommended Practice Resources:

These are several resources I recommend to help you improve and practice your computations and data interpretation.

Math Computation Resources:

CaseInterviewMath.com – This is a FREE math practice tool I developed for practicing 1) arithmetic for speed and accuracy and 2) estimation math with large numbers. This tool compares your math accuracy and speed with other CaseInterview.com members and to my own test results as a benchmark. This helps give you an idea of how your math skills compare with others.

McKinsey Imbellus Game FAQ

OUR CLIENTS SAY:

"I can hardly overstate the importance of getting the math right: the feedback on my 35+ (practice) interviews was consistently good regarding my math skills. Thinking out loud, calculating out loud, making clear notes and calculations have really helped me to involve the interviewer into the case. Your math tool on the website has actually been the sole resource I used to improve my math skills. "

"Thank you so much for all the effort you put in creating such a great platform for case interview preparation! Needless to say how much all the materials you provide are useful to prepare for interviews in Management Consulting. I clearly doubt I would have gotten an offer from McKinsey without your help."

"I received offers from McKinsey (Singapore) and Bain (China) during the past recruitment season. Without your materials, it would be impossible for me to get the offers. I have decided to accept McKinsey's offer which gives me more opportunities to work on public sector projects. Thank you again."

"After my first round interviews, I was told to focus more on my math (I was a bit slow and made some small, but still unacceptable mistakes) so over the course of 3 weeks, I practiced math on CaseInterviewMath.com by doing about 6 tests a day. I started off at 94% accuracy and 7 questions/minute then maxed out at your record of 100% and 18 questions/minute. This DEFINITELY helped me do math accurately and simulated the stress I felt during the interviews."

"Thank you being a coach to myself and so many of your other readers. Your courses helped me earn a role at McKinsey, where I am a 0+4 BA. When I receive phone calls from prospective consulting hires, I ask them if they've heard of Victor Cheng, and recommend they take a look at caseinterview.com. As I continue to develop my career and personal life, I plan to continue to use your materials, read your newsletters, and learn to grow. Thank you then for all you've done to help me get where I am today, and for what you continue to do to help myself and the rest of your readers grow."

"I got a McKinsey offer in the Boston office on Friday (three days ago) Tons of thanks to you (I used all your resources, in some form or the other). Thank you for putting all that information out there! "
