Tech is one of the hottest industries out there.
But what companies are able to live up to the hype and keep their top talent happy?
Job site Paysa recently released a report breaking down which tech companies were able to recruit and retain the best employees from April 2016 to April 2017.
Paysa tracks employee movements with its CompanyRank machine learning technology, which analyzes nearly 7.45 million points of data including résumés, job postings, and social activity across the past 15 years from 198,000 companies.
An employer’s CompanyRank score improves whenever someone joins the company from another top-ranked company and declines as employees leave and the company repopulates with talent from lower-ranked companies.
