Pros
Stable company compared to other pharma companies. The cafeterias are pretty good and the stock plan is the best benefit you will receive from Gilead. There is a pro and con regarding work life balance. You gain ton of experience because you are able to work on multiply projects and different roles.
Cons
The biggest issue with Gilead is half of the employees have been with the company for 10 plus years and do not understand it's not the same small HIV biotech anymore. Their are not very strategic and majority of the time resistant to new ideas or changes. Science runs the entire company which is great however its still on publicly traded company and they need to ramp up their commercial capabilities to play with the experienced big pharma powerhouses. Its a very competitive environment, turf wars, and stakeholders that are extremely immature to the point they will sabotage your career for the sake of keeping the status quo. And they are not kidding when they say its lean. There is no work life balance at all this is that old way of thinking mandated by the CEO
