Avantages
Global workforce of engaging people who are talented and collaborative. Changing roles often means you are never bored. No skimping on ergonomics, safety, or making travel tenable. Pension and 401k match are great... why most people are still there.
Inconvénients
If you are not in the top 10% 5 years in your best option is to leave. Company prepares you to work only for them as it is hard to be a specialist. DS expats are reserved for Canadians and Europeans or executives. Basically everything is focused on the top 1%, with no effort or planning for those that actually do with work and no aknowlegement that the pay is lower than equivalent responsibility in other companies if you are not on the golden ladder. Company is not promoting minorities or US women, but creating at the same time a feeling that white men cant get ahead because they are not one..basically the worst of both.
