Hello,
Here are my thoughts on EYP generally and some thoughts on the DACH region:
1) Prestige wise, I would say EYP is generally Tier 3. Tier 1 being MBB, Tier 2 being Roland Berger, Oliver Wyman, etc. EYP worldwide is generally comparable to Strategy& and Monitor Deloitte. Bear in mind this has an implication on all the following points.
2) Main types of work: There certainly would be some strategy projects, but typically with T2/T3 companies. There will also be a lot of implentation support, operational projects with T1 companies.
3) Strongest industries: For DACH region - I do not know specifically for EYP. But my guess is that they would be relatively strong in the industries heavily concentrated in the region (manufacturing, automobile, etc)
4) Exit opportunities: Definitely possible to switch to T2 firms locally. Can also switch to T1 firms in high demand geographies like Middle East / Australia.
5) Comp and benefits: Its certainly lower than T1. For exact figures, might be helpful to check out glassdoor for the exact country you are looking at.
All the best!
