Pros
Extended Benefits give you some (Taxable) extra cash Good for grads and interesting projects (Outside of ERP) A lot of training things if you're on the bench. No chance to use it if you're not.
Cons
Again Speaking from the ERP Practice: - No Culture or effort to get people from the practice together. - Management will not be interested in you - A large number of very experienced consultants across Europe, but again due to lack of a community, you´ll get no help - Easier to get a new job than to go through the promotion cycle - HR really isn't interested in you - They list a career mentor as a perk. Don't be fooled, this is just your line manager. - More money is spent marketing on D&I marketing than actually making it a nice place to work for everyone - No bonus or pay raise even with high growth and huge profits
