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

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.

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 :)

Hi there,

A bit concerned you're asking for advice 1 day before...not really enough time to properly implement whatever we say. Concerned about what this level of readiness for the assessment reflects on you in regards for any future case interviews you'll have (read: you need to change your behavior to succeed here).

Anyway...

All of these tests are very similar.

Format? Somewhat. Content and what's required from you ability-wise? Not at all.

The best way is to really find online tests / questions and practice. Regardless as to whether it's a new or old test, the principles are mostly the same:

  • Time management (need to think quick)
  • Business knowledge/context (incl key formulas)
  • Critical thinking (answers that are very similar to each other... clues "hidden" in the text)
  • Ability to interpret data/charts

Think of it as a merge of a case and the GMAT/GRE.

You need to be clear on some key case related and accounting formulas (margin, growth, breakeven, etc) as well as be good at critically understanding the question (including nuance to questions) and parsing through complicated text with a fair amount of distraction.

You'll also need to be good at chart/graph reading.

The (old) McKinsey PST, BCG Online Test, Bain SOVA test, etc. are all quite similar so leverage resources across all of them.

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.
