Pros
I learned a lot, I grew a lot. Colleagues were lovely for the most part. The science is sound and innovative and there's a lot of work being done there that could make a huge difference in the long run. I felt like I was part of something important.
Cons
What a mess. Org chart changed every 5 seconds. In 2 years we had 3 CEOs. Salary was well below industry standard and we were regularly expected to work more than 40 hours a week even though this time was uncompensated because we were exempt employees. There was also a huge communication divide between the labs and the offices- expectations/timelines were often placed that were so tight that they were either impossible or doomed from the start. The ignorance? denial? was so pervasive that they didn't see the issue when 3 people quit in one week.
