Pros
They do allow you as a technician or engineer to take some level of risks, not everything is done as per a documented guideline, there is some reward in that.
Kontras
Micron won't admit that the downturn is over and there's opportunity out there. They did not give me a raise in 4 years of employment. Rather, they forced me to salary so that they had complete control over me. Benefits continue to get stripped from the employees and the health care package is one of the worst I've seen. Select people get put on the fast track and their promotions outpace everyone else's by a rate of 3 or 4 to 1. If you just want to get some 300mm experience and use them as a stepping stone, that's all I would recommend. Micron is not a place to grow your career or advance, unless you know the right managers and can get in with the right crowd.
