Pros
Gilead is a company that really makes a difference with their products. They also have many great benefits though not anything extremely special. Gilead has some of the most talented individuals I have ever worked with. The work life balance is quite good and they have multiple events every year that include family.
Cons
While Gilead has some great resources, IT doesn't know how to keep them. To get promoted you have to leave and come back a year or two later. The IT department also has new leadership that has no problem splitting hairs by saying what you want to hear but hiding the negatives they know they are going to do. The company line is "we run lean" but in IT it is more like anorexic and because they drive away their top talent it makes it worse since there tends to be a large portion of the resources that are still ramping up.
