Pros
Good salary for the Madrid average, and if you are lucky, you will learn a lot in some proyects in the main spanish banks. The mates are incredible, and there are a lot of great and very smart people in the company. Good salary increases (10-15% each year)
Cons
Management is awful in 90% of the cases. Their only worry is to win money selling projects, no matter how the project is sold and if the final product is something valuable. There is a lack of middle-management people in the company, as they have a lot of junior consultants, and a lot of partners and top-managers. Of course, we are speaking of consultancy, so do not expect exiting before 8 p.m., and 11 is common. Not common, but possible, is to work till 11 p.m. and some weekends.
