Pros
Sanofi has incredible products. Best in class drugs. Position has decent pay and very nice Benefits. Rep positions offer you Flexibility to maintain a decent work/ life balance.
Cons
New product launch strategy is a comic book. I have never seen a more confused sales force due to strategy set up by upper management. Company is so big it has no grasp on whats happening where rubber meets the road and its sales model is resulting in frustrations with sales force and overall underachievement of company goals. Career advancement is slow but if you know right people you can find the limited opportunities. Like with other pharma companies, sales team is always looking over their shoulder for layoffs and rumors right now are that 2016 might be a brutal year.
