Pros
It had all the key functions of a typical job and was a reliable means to an end, as it continued to provide me with a regular paycheck.
Cons
It was overall a mess, with no 'clear structure in place for employees to advance their career or meet their career goals. The company seemed very bogged down in hierarchy and internal politics, making it hard for senior management to make effective decisions or support their subordinates. When things went wrong, and to cover up the inadequacies or mistakes of senior management, certain employees would become the scapegoat and be blamed, blackballed, or bullied instead. Oddly, in some groups, such as Medical Writing, it seemed junior writers were given responsibilities or complex cross-functional initiatives to take on that would typically be done by more experienced writers at other companies; this seemed to result in a lot of confusion across the board when Medical Writing was interacting with other functions at the company. The different functions at the company also seemed to worked in silos and it was NOT collaborative, which seemed to stifle innovation and creativity, and prevent any real progress from happening. Working at Biogen seemed like a waste of time, as it felt more like we were just turning the wheels of a car to keep it going, but not doing anything more to make it work better (ie, upgrades, repair). I saw no promise in this company.
