Experience hire span from Associate to Associate Partner Level, and of course competences vary among these roles.
There is no favourite company / function, since they like both experts in fields they are already working in as well as sectors / functions they are interested in enter into.
I would roughly consider these as previous working experience (very roughly):
- Associate: 4-5 years
- Engagement Manager: 5-7 years + leadership position in previous company
- Associate Partner: 7-15 years + leadership position in previous company
