On-demand Go, Scala and Ruby, top-notch Python and JavaScript

If you have the skills, Go, Scala and Ruby are the programming languages ​​that will most likely lead to job interviews, although JavaScript, Python and Java are the most commonly used languages.


According to Hired recruitment data, Go was the most sought-after language last year, offering 9.2 interviews on average over a two to six week period.

Scala was the second highest in demand (8.5 interviews) followed by Ruby (8.2) and TypeScript (7.9).

The number of interview requests in all languages ​​has remained almost constant from year to year, said Hired, without changing the way each language is ranked relative to others. "This could indicate that supply for these skills has not yet met demand and we can see a steady stream of applications as more and more engineers are learning Go," the recruitment company said.

In its Software Engineers Report 2020 report, Hired said the most demanding programming language varies with experience: if you are programmer with four to six years of experience, Go skills will provide you with most interviews, but Ruby engineers with six to ten years of experience are equally in demand. Developers with over 10 years of experience are at the top of the pyramid if they have Scala and Go skills. The company noted that software engineers with 10 or more years experience 20% fewer interview opportunities than those with four to ten.


There is a big difference between what employers are looking for and the languages ​​that developers feel comfortable with. JavaScript is used by 63% of programmers surveyed, followed by Python (44%) and Java (38%). The tenants said that these languages ​​are favored because of their useful and well-maintained libraries and packages. Kotlin, Objective-C and R are the least used languages. THE Python, JavaScript and Java were considered the most popular, with Ruby, PHP and Objective-C being the least liked.

According to Hired, the fastest growing roles in the tech industry include artificial and virtual reality, games and innovations. The profession of one Blockchain engineer - last year's fastest growing role - has fallen low on the charts, possibly reflecting the way this popular technology has retired. The recruitment company said the data came from more than 400.000 job interviews and job offers from the previous year, from 10.000 companies and 98.000 job seekers.
