Pros
Benefits are great. Micron has their own internal "university" to help their employees learn desirable skills, from programming and code, data and leadership to dealing with stress and mental health issues. They offer paid therapy through a third party for traumatic life events. The list goes on. The culture has stagnated some as they've injected more and more politics. I don't necessarily disagree with the stances taken, but like many have said on the internal message boards: "Can we please stick to making memory?" That said, the culture is still above average.
Cons
The sense of self and individuality is lost with such a large company. They try to prevent that, but I'm not sure there's much they can do. Also, global policies outrank the individual, so innovation at the local level is stifled. Micron is beholden to various groups that include the likes of Amazon, Walmart and other global Mega-corps. Their business decisions are obviously impacted by this. Although not always bad, they tend to favor the business without regard to the individual. One example would be Micron being forced to take a stance on a big event that happened without regard to the nuance and the feelings of individuals on both sides. Another is the pandering to certain groups, which has become in vogue for big business as of late. I'm all for equality, but don't pretend like it isn't about the moneys. Especially when leaves large swathes of your employees feeling left behind.
