Technology companies losing talent at an alarming rate

See the 24 technology companies who are losing talent at an alarming rate recently around the world and they will surprise you.

There are countless opportunities in the world of technology, but not all tech companies are created equal when it comes to retaining top talent.

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, and which struggled to keep the best employees on board.

Paysa tracks employee movements with its CompanyRank machine learning technology, which analyzes nearly 7.45 million points of data including resumes, 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.
