Pros
Work load varies sometimes more sometimes less. Managers usually pretty reasonable about time off requests. Recently increased from 2 to 3 weeks of vacation per year for new hires and added a buyback option for unused vacation.
Cons
Negotiate hard for higher starting pay because once you're in you're only getting marginal increases. Career progression is slow and dependent on relationships more than hard skills. Training is trial by fire far more often than anything formal. Lots of people coasting by while others work hard and get practically nothing but experience in return. Yearly "PPP" reviews are practically pointless and dont make much of a difference in your pay. Company loves to give out 2-3% "raises" per year which amount to nothing more than cost of living adjustments when you factor in inflation. Certain departments and jobs are hard to transfer out of once you're in. Management is a mixed bag some good managers but most are not. It depends on the managers market segment. Many good people have quit over certain managers.
