Vantaggi
Good benefits, incredible CEO, exciting potential and growth translates to career opportunities if you're in a group that allows you explore other roles in the company.
Svantaggi
Very difficult to explore new opportunities if you're in the creative department. There's a real absence of leadership and management talent there. The atmosphere has been incredibly negative and political for the past 3 years, so if you're interested in another role you'll need to leave the company (you'll be given that advice if you express interest to your manager). The department is purposely trying to become an ad agency, except the department leads don't want to partner with other teams and are openly adversarial when they're not in front of execs. The department leads set a bad example by frequently talking trash about colleagues outside the creative team and that doesn't help anyone. If you're considering leaving your agency gig to take a client side role, this is not the place you'll want to call home.
