Pros
Company initially boasted a very open, accepting work culture that valued its employees. Employee resource groups existed across various areas (which is an improvement over an utter absence of ERGs in some places), benefits were very good, and the employees that I worked with were great, hard working people (for the most part).
Cons
Company mismanagement of programs, employee hiring, and funds led to catastrophically unsustainable financial situation during the latest biotech stock downturn. The original executive leadership essentially could not effectively strategize the company's research & development efforts in an effective manner. Combined with unsustainable hiring without any checks resulted in a massive restructuring that was triggered by overhaul of the CEO and some other executive members. The worst part is that the employees paid for the mistakes of executive leadership made over the past decade, and were punished for their hard work by mass layoffs, bonuses cancelled, pay raises/promotions cancelled, etc.
