Pros
For young professionals starting out its a step in the door to work at any company around the world. Its a great place to take advantage of their training programs and grow as a business professional. Working at this company will produce opportunities that others who did not work in public accounting/big 4 will not have.
Cons
You will work more hours than you thought possible mostly with people who do not speak English. Clients will hate you automatically before they even meet you and you will be expected to work ridiculous hours because your part of the "team". It is impossible to make a career at this company unless you hate your family and don't want to have a life. No matter how long you stay at this company your workload will only increase, Partners work day and night and expect everyone to do the same.
