Oliver Wyman Virtual Assessment

Hi all,

 

Going to take the Oliver Wyman virtual assessment tomorrow. Does anyone have any tips/ways to prepare for with this assessment, especially the numerical reasoning part?

 

Thanks

Hello there, 
Good luck with your assessment tomorrow. While I have not done the OW virtual assessment myself, I would say that almost all numerical reasoning assessment are similar as of they check your ability to define simple steps to solve complex problems and your arithmetic skills of subtraction, addition, multiplication and division. You would get problems related to profitability, growth rates, market shares, weighted averages, e.t.c.

You would need to sharpen your skills across those dimensions and if you still have some difficulties, then you might need some professional help in identifying what exactly the development areas are and how to overcome them.

I hope this is helpful,

Regards,

Sherif

hey there :)

for the Oliver Wyman virtual assessment the key is speed under pressure rather than complexity, especially for numerical reasoning, so I’d focus on quick mental math, ratios, percentages and interpreting charts fast rather than over-practicing heavy calculations; what helps most is practicing under strict time limits, rounding aggressively to get to answers faster, and always checking what the question actually asks before diving into the data since many candidates lose time there, also stay calm if one question feels messy and move on quickly because performance is relative, overall if you’re solid on basics and manage time well you’ll be in a very good spot

best,
Alessa :)

The numerical part is not hard maths. It is time pressure and format. That is what catches people out.

Do one timed practice test using SHL or Korn Ferry. Do not practice without a timer.

In the actual test: read the question first, then look at the data. Most people do it the wrong way and waste time. If a question is taking too long, skip it and come back. Do not burn time on one hard question and miss easy ones.

Oliver Wyman also tests logical reasoning and sometimes has a written or video component. Keep your thinking clear and structured.

Google for past examples of the test and practice as much as you can. Then get a good night's sleep. That's as much as you can do if the interview is in one day. 

For future interviews, if you have more time, there's a lot more that you can do - building a fast maths base, learning terms, practicing different versions of the assessment, etc.
