Cons
Office culture is so laid back, people have no motivation to perform and tend sometimes to forget clients are kings. Promotions are based on clanic friendship and not added value recognition. Salaries are not competitive after 4 or 5 years of experience. A huge turnover forces to re-explain again and again the same thing to newbies.
