Pros
Stay if you are already in retiring age, or you don't want to develop your career.
Cons
Working as principal engineer at Microchip for 3 years by far, I have to say this company is a dirt cheap place for working, which is the real company culture, no matter what it says on its website. Microchip claimed that the biggest strength is its employee, however, it treats its employee awful, such as very low pay, few salary increase, joking 401k plan, etc. This is definitely not the right place where you can develop career skills in a long term view since its technology (both Analog and MCU) is far behind its competitors. Most of the principal engineers and managers idle away their time, and many motivated engineers keep jumping to the other leading technology companies for much higher salary,way better benefits, wider career developments, etc. To be honest, after staying for just a couple years, you may lose your motivation. After staying more than 7 or 8 years, you may lose your technical ability to jump for another good job. And, finally, if your expertise is in the field of Analog, please stay away from this place!
