Final thoughts

Unsurprisingly, Chinese businesses take up several slots on the list, but the US retail giant Walmart continues to reign supreme in a combination of profits, assets and employment opportunities.

Jobseekers should consider the multiple benefits of working for large companies, including job stability, career development possibilities, and the ability to work internationally.
