Pluspunten
Once people make it to director level in marketing, work-life balance is typically quite good(10 years to get there). Vacation policies are good for some, but not all. You get to experience a broad variety of roles within marketing on good products and projects. Some roles provide exposure to executives and fun conferences.
Minpunten
The data systems are not being modernized to keep up with reporting demands or the needs of modern marketing. Accurate data on sales is not easy to get your hands on. Only a select group of marketers are trusted with data though nearly all have graduate degrees before being hired. In marketing, promotions are simply based on time with the company. If you're an outstanding employee, there is nothing you can do to accelerate your career. Post-mba, it's likely 15-20 years to get to VP if everything goes perfectly. On the flip side, those with less drive and talent get promoted at the same rate as everyone else.
