Overall, my experience has been pretty good, but a few cons to watch out for: - The workload can be heavy - this is not a place to work if you are looking for strong work/life balance. - The culture can be intense and if you don't have a really good relationship with your boss, it's difficult place to work. It feels like a lot of fear-based leadership, from the top down. - A lot of managers are new managers, and many don't have training in how to manage people. There aren't currently formal ways to provide feedback in a safe way about managers either. - There is a strong focus on learning, but not necessarily clear career growth paths. It would be great to see the focus shift so that it's more tangible for how your career can grow both in and outside of Moderna.
