Vantaggi
Because it is so large there are opportunities to switch departments internally pretty easily. Good WLB as it was mostly remote when I left. Caveat, this may not work well if you are a young professional looking for the "office" experience.
Svantaggi
Average benefits, minimal diversity, and below-market compensation. Not many young professionals, mostly family aged workers. C-suite could be more transparent about hot topics and need to articular clearer sense of goals and directions during quarterly calls. Worked with some wonderful people and some superstars, but certain groups have toxic management. They perpetuate a cliqueish/ groupie mentality and you are protected if you are well liked by management but if not, you are generally first to go during RIF. Departments seem to "change structure" too often. Company seems to respect people with long tenure and will place them in roles if affected by RIF.
