Vantaggi
It is a great professional experience. There is a lot of client facing. It is very common to perform a role above your position (i.e. Analysts to play Consultant roles, Consultants to play Manager roles, and so on)
Svantaggi
Compensation is unfair. It is almost half of market average. Over hours are demanded every day but they are not paid. It is almost impossible to have a feed back from your manager. Though a process is in place, leadership just refuses to do it unless HR formally requires so. The evaluation process is very subjective. Though you are evaluated against the objectives you set with your manager, other leaders that never worked with you can influence your final grade. So, during the meeting when the grades are set, the mentors that shout the most obtain the better grade for the mentored, and your real performance is almost not taken in account.
