EY-P Strategy and Transactions case study

Hi everyone,


I am preparing for a case study interview for an internship at EY-P. The format includes 15 minutes of preparation followed by a 45-minute presentation and interview.

Does anyone have experience with this specific format? If so, could you share insights on what to expect and how best to prepare for it?

Thank you very much for your help!

Hi Bruna,

First of all, congratulations on the invitation from EY-Parthenon!

I would be happy to share my thoughts on your question:

  • First of all, yes, I have helped many of my coachees succeed in written case studies, whether at EY-Parthenon or other consulting firms. As the most experienced coach in terms of consulting, interviewing and coaching experience, I'd be more than happy to help you with it.
  • Moreover, written case studies are generally not very different from regular case studies, so I would advise you to prepare just as you would for regular case studies. Please also note that you may be even more responsible for your own time management and that you should practice your presentation skills.

You can find more on this topic here: How to succeed in the final interview round.

If you would like a more detailed discussion on how to best prepare for your upcoming EY-Parthenon interviews, please don't hesitate to contact me directly.

Best,

Hagen

Hey there,

For the written case practice I'd recommend you to look at regular case interview samples (there is a ton here on PL) and then work through them on your own. Look at the prompt and core question you are trying to solve, then look at the data provided and work on your recommendation.

Follow these rules:

#1 Already have a plan when you go in for the written case

Since time is usually limited, you should have a plan on how long you want to spend on each task of the assignment beforehand. For practice, use 20 minutes for the analysis and 5 minutes for the recommendation communication. For the real case adapt accordingly based on the time budget provided.

#2 Focus – quickly separate crucial information from the noise

Written cases usually present you with an information overload that you need to sort out

#3 Graphs and charts – interpret and distill key insights from graphs and charts

Written cases bombard you with charts, graphs, tables, and other visual depictions of data that you should use to test your hypotheses. Learn how to quickly read and interpret them

#4 Math – quickly draft equations and conduct pen-and-paper math

Get into the habit of quickly setting up and simplifying calculations

#5 Storyline – draft a compelling storyline and tell it with visually appealing outputs

Create a top-down storyline of your recommendations. State your primary recommendation, then use supporting arguments to strengthen your position

#6 Presentation and defense – communicate and defend your recommendation top-down

If you have to present your findings at the end of the case, follow the top-down approach of your slide deck. Be confident and engaging when going through your recommendation and supporting arguments.

All the best!

Cheers,

Florian
