Vantaggi
Regeneron as a company is driven completely by metrics. Every candidate is on an equal playing field for a promotion as technical skills and completed work serve as the primary metric. There is very little value placed on soft skills, but this situation means that Regeneron is by definition an equal opportunity employer.
Svantaggi
The company is growing rapidly, but most of senior management has been there for an extended period of time. As a result, there is not a lot of space for vertical growth. Additionally, because Regeneron is so metric driven and places little emphasis on soft skills, management is not highly skilled at "managing". A lot of senior management are simply individuals who have amassed a large amount of technical information . The best managers in terms of driving the development of employees are not always in charge.
