Pros
Working with state of the art technologies such as 5nm process. Contributing to state of the art ICs. Not all gropus are as stressful as Silicon Engineering. Might be a good place if you like Apple products. Could be good for junior engineers to gain experience before moving to a more interesting job.
Cons
Micromanagement on all levels drove me to a quick bunout and eroded my self esteem. My most productive time was when the boss was on holiday. Too much time spent on planning and reporting compared to time used for work. Corporate brainwash. HR completely useless. Often isssues are passed from one to another rather than working together to solve them - this is common in large organisations. Very tight schedules leave no room for much inovation and personal growth. Spageti legacy code passed from project to project with little time to clean it up. Teams spread across different timezones around the world might result in many meetings at odd times.
