Hi Anonymous,
the usual process at Parthenon EY consists of:
- First round based on case + fit
- Second round based on:
- Case + fit
- Group presentation (prepare in team a 30-min presentation for MDs)
As mentioned by Hugo, you can prepare for the first round using the material you have already found for MBB. As for the group case, my suggestions would be to:
- Don’t act necessarily as the group leader unless you are a natural one; you can get points for leadership as simply as helping the natural leader to manage the process
- Contribute helping to (i) structure the process; (ii) do double checks on math/analysis; (iii) respect the time allocated
- Be friendly and help everyone to participate in the discussion, in particular if you see that someone is not involved
Best,
Francesco

Be prepared for lead case interview. If you are prepared for MBB, you will get the offer.

Hi,
I wrote some advice here for Accenture group case:
My advice for the group interview:
- Don't take a leadership role trying to organize and manage other people unless you are a 100% natural leader
- Act rather like a contributor with: a) frameworks to structure the problem b) rough calculations c) Industry / functional knowledge (it helps to be a background in marketing or supply chain) d) creative ideas
- Be nice and friendly with everyone and don't try to show that you are better than others. Rather impress with contribution and impact
Good luck!

Any advice for a Parthenon-EY interview (UK)? Thank you!
Hi there,
The case is quite similar to MBB, yet less comprehensive.
Prepare like for the top company.
Cheers,
Alex

The “typical” case includes
- Structuring
- Market Sizing
- Growth Drivers on the market/How to grow the business
- Chart interpretation
I have some recently retired cases from EY-P, and organize sessions based on those, so let me know if you are interested.
