From the Salesforce Blog:
New technologies are creating new jobs globally. The Salesforce ecosystem alone will create 2 million jobs by 2020—covering a broad spectrum of business and technical career paths. Unfortunately 80% of companies struggle to find skilled talent to fill these jobs. The loss in productivity caused by this skills gap costs companies a staggering $1.3 trillion dollars per year. While students should be a great source of new talent, employers say recent grads don’t have the skills they need.
