How hard is it to get promoted at Biogen?

Promotions within the organization are hard fought for. Upward mobility is often only acheived by transferring out of your internal organization into another role. Work /Responsibilities is not always aligned with title and compensation package. Tenure and relationships play a large role in career growth.

Not as hard as you'd think, internal growth is strongly encouraged and learning is fostered. There are plenty of internal growth opportunities available, but you must be proactive.

Very hard/impossible.
