Want to work for the world's tech giants? You'll need a particular set of skills

You'll need a very particular set of skills if you want to get a job at some of the most competitive tech companies out there.

Just look at the data compiled by job site Paysa. The site has reviewed tens of millions of résumés, provided by a combination of Paysa's partners, recruiters, and users.

Paysa took a closer look at the résumés of people who work at Google, Apple, and Microsoft, to get a sense of what skills those employees had in common.

All three companies made Business Insider's list of the best places to work in America. Microsoft employs 120,849 people; Apple's workforce weighs in at over 100,000 people; and Alphabet (Google's parent company) has 61,000 employees.

If you want to join any of those workforces, it definitely helps to know what they're looking for.
