Could someone explain to me a bit more about OW presentation interview in which a candidate is provided with lots of data to analyze and asked to do a 30-minute presentation? It looks like this requires some knowledge of data science. What kind of analytic softwares are you provided? Excel, R, etc? How much time do they provide for data analysis before the 30-min presentation? What are they looking in the quality of data analysis? What is the best way to prepare for this type of presentation case?

For a presentation interview you are usually provided with a pack of 20-30 slides that you need to analyse to answer questions using 4-5 slides and present them to your interviewer.
In order to crack the interview you should consider the following points:

  • Prepare for a traditional case interview: the competencies and the problem solving skills requested are pretty much the same
  • Define a plan of action according to the time given: one of the most important aspect of these cases is the ability to manage your time. You should consider the followinf steps: Initial reading, decide the approach, analysis, slides and final review.
  • Train quick reading skills and maths: there are a lot of good sources online, even the GMAT integrated reasoning section could be good.
  • Train slide-making skills: this is a crucial part because, as consultatn, slides are your most important communication tool. Be aware that there are some "golden rules" that you have to consider for making slides as a consultat. You can find something online but feel free to contact me for a quick analysis.
  • Learn how to present slides in an effective and professional way

You can find some good examples of written cases online, but I could forward you what I have. Contact me if you are interested.

Hope it helps,

Hi there,

It is similar to the written case interview that some other firms (e.g. BCG, Bain) have been using in some regions.

You can find useful information on written case interview on these companies' websites. Also here on PrepLounge you can find quite some past Q&As that can give you a good idea of how to tackle written case, just search by key word "written case".

I have 1-2 example cases. PM me if you want to do a practice.

case preparation will be the classical one with 2 additional points to focus on:

  • 80-20 prioritization: quickly navigate an important amount of data to find what really matters to the case resolution;
  • Executive summary: develop 1-2 pages to present that sum-up the problem and your recommendations.

I have a couple of well done written cases, feel free to text me for sharing.
