In today’s digital world, job seekers are savvier and more informed than ever.  Anyone with an internet connection has access to employee reviews that deliver insider perspectives on a company’s culture, compensation, advancement opportunities, management and the best global destination for employment.

According to Santa Fe Relocation’s 2017 Global Mobility Survey, which surveyed nearly 1,000 global mobility teams and business leaders in 56 countries, the U.S. once again tops the list as the most popular location in the world for international work, followed by China and the UK. The U.S. also remains the number one destination for relocations from the UK, as well as the predominant origin country for people moving to the UK, according to a customer study from Sterling Relocation, a leading relocation management company.

Employee reviews aren’t only relevant for professionals evaluating their next career moves and where they choose to relocate.  Leaders of top companies can also look at the reviews to gauge the effectiveness of their own infrastructure, learn how they compare to their competitors, gain insight on how to improve the employee culture, and attract the best talent from around the world.

So who are the best companies to work for in the U.S. that are attracting job seekers?  According to Forbes’ Fortune 500 list — the 63rd in the history of the ranking, the top ten in order of rank are Walmart, Berkshire Hathaway, Apple, Exxon Mobile, McKesson, UnitedHealth Group, CVS Health, General Motors, AT&T, and Ford Motor Company.

Companies are ranked by total revenues for their respective fiscal years. Included in the survey are companies that are incorporated in the U.S. and operate in the U.S. and file financial statements with a government agency. In total, Fortune 500 companies represent two-thirds of the U.S. GDP with $12 trillion in revenues, $890 billion in profits, $19 trillion in market value, and employ 28.2 million people worldwide.

Contributing to its position as the leading global work destination, the U.S. is also currently the second most competitive economy in the world, climbing to an eight-year high in global rankings, according to an analysis published by the World Economic Forum. The latest edition of the Global Competitiveness Report, an annual ranking of 137 countries based on data from international financial institutions, moved the U.S. up from the number three position to second place, just behind Switzerland.

“Successfully meeting institutional challenges relating to both public and private institutions, improving the macroeconomic environment and investing in human capital — particularly in the areas of health and primary education — will be crucial for the United States to maintain its position near the top of the competitiveness rankings,” the authors wrote.

Although the U.S. leads much of the world in higher education, job training, quality of companies, market size and technological capabilities, companies must also continue to prepare for a coming wave of automation, which is expected to create a surge of computer-related jobs while eliminating low-wage positions.
