This article describes Emsi research into the top ten in-demand skills U.S. Fortune 500 companies were seeking in employees. To do this, Emsi looked at the top ten companies on Fortune magazine’s 2020 list and pulled data from millions of their online job postings, comparing them by company, to uncover the top ten skills these companies sought from 2017 to 2019 and how those skill demands have changed over time. Findings show that skills such as communications, management, and leadership consistently top the list, followed by customer service, operations, and sales. The article shows data from each of the ten companies displayed in a flow diagram illustrating the change over time from the first quarter of 2017 to the second quarter of 2019. When Emsi researchers compared the top in-demand skills data from these top ten companies to all companies across the U.S. using online job postings, they found the same skills consistently identified.
