Pros
I have had good opportunities to continue to grow in my career while in Micron IS. I'm able to suggest new ideas (however I must be very cautious not to be seen as going against the grain, and getting traction on these is very difficult. Also, little credit is given back when traction is finally gained - usually after at least 12 mos).
Cons
Work life balance is very company oriented. Very limited ability to work from home and overall WFH has a negative perception when it comes to promotions or abilities. There is a trust issue between management and non-management team members. Management has difficulty monitoring employees based on productivity, and instead uses the "onsite badge report" which shows when you're actually working from a Micron facility. If you're working from home, that is seen as welcome but not part of your 40 hour work week, and in reality Micron really wants more hours from any non-management employee than could be ever possible. There are more process responsibilities assigned to team members than could ever be followed (at least while still keeping productive on real work), and policies are written for the lowest productive employees instead of the higher performers. There is always too much work in the pipeline than feasible, and it's more of a "yes-man" oriented culture than one that makes decisions based on hard numbers. On a postive spin, the company is working to improve on some of these areas.
