Avantages
It pays the bills though the salary is not competitive with the Big 4. Light work load. Not very demanding. Easy to look good if "you have brains in your head and shoes on your feet". You can take your vacation almost without question. Staying past 5 is an exception. Use a couple years of audit experience to prep for the CPA and move on.
Inconvénients
Study the history. Its Crowe Chizek, a small city, office centric, passive aggressive culture that began in South Bend not London. The second office was where??? As far from a meritocracy as you can get. You will serve time in grade. An aggressive personality does not fit in and you will know it. You wont learn much (think small town accounting firm) and you wont have a mentor or role model. Very little opportunity for foreign assignments. They are pack followers and not leaders. Doesn't buy you anything on a resume.
