Coding Dojo research reveals hiring limitations of learning a single coding language

Coding Dojo, a premier coding school for aspiring software developers based in Bellevue, recently released results of its research into coding language requirements for job openings at the largest U.S. companies.

It found that none of the top 25 companies in the Fortune 500 use just one coding language for products and services, and that on average they rely on four different languages.

“Much like any tool or application, companies use different coding languages for different requirements; there’s not a one-size-fits-all option,” noted Coding Dojo Head of Curriculum Speros Misirlakis. “While specific jobs might focus on a particular language, this research shows that a single language could be a long term dead-end. Aspiring and existing developers must learn coding’s common building blocks and ultimately become fluent in multiple languages to have the adaptability and flexibility for a successful career.”

Coding Dojo found that JavaScript is the most listed coding language in software developer job openings at Fortune 25 companies, followed in order by Java, Python, Ruby and Perl. Java, a 20 plus year old server-side language for back end development, is likely the most popular overall – all Android apps are based on it and technology analyst firm IDC says 90 percent of Fortune 500 companies use Java.

Coding Dojo’s research shows the following hiring plans for software developers at the Fortune 25:

Methodology

In order to arrive at its findings, Coding Dojo analyzed the coding requirements for all software developer listings for the top 25 companies on the Fortune 500 on job website Indeed.com in early December 2017. Three of the Fortune 25 did not have developer openings listed at Indeed.com during that period.
