Vantaggi
Great benefits, opportunity to gain valuable career experience in a variety of roles - an ideal place to start a career, many talented people, prestige of working for a company highly regarded[less so now] as "cutting edge" in its day.
Svantaggi
Job secruity seems to be an anachronism. Like many large companies in the last 10+ years, management has moved to an out-sourcing model in many areas, especially in IT which makes everything "go" . The hoped for longterm efficiencies haven't been realized - phasing out/displacing functions in the west to outsource to an allegedly cheaper workforce. There's a serious knowledge drain no one seems to be doing anything about. This directly affects the quality of customer service which was the hallmark of this great company.
