What’s the Most Popular Programming Language on CodeSignal?

For engineering roles, candidates typically are available in with expertise in all kinds of languages. Nonetheless, after hundreds of assessments run on CodeSignal, we’ve seen clear winners among the many hottest languages candidates use to finish them. As a part of learning the lingo, this record will allow you to get accustomed to related programming languages and the place they’re used.

Language Recognition

Diving proper into the info, listed below are the most well-liked languages utilized by candidates on CodeSignal:

  1. Python: 35.4%
  2. JavaScript: 22.8%
  3. Java: 15.5%
  4. C++: 6.2%
  5. C#: 5.5%
  6. MySQL: 4.3%
  7. TypeScript: 1.4%
  8. Swift: 1.3%

Let’s break this down and speak about why candidates would select these languages.

Python is available in at primary, making up over a 3rd of our interactive evaluations. Whereas that’s a big share, it is sensible—given a alternative, many candidates select Python for its simplicity. It’s generally identified and taught, it’s relevant to many domains, and it’s straightforward to work with. Python applications typically require writing much less code than different languages like Java or C++. With its nice synthetic intelligence and machine studying libraries, and a strong neighborhood of specialists, Python can be common for information science candidates.

Subsequent is Javascript. This language is usually utilized in internet programming and cellular apps. Javascript is usually used to construct interactive frontends, particularly utilizing frameworks like React or React Native. It will also be used to construct backends utilizing frameworks like Node.js. 

Given the demand for internet and cellular builders, it’s no shock many groups want to judge candidates’ JavaScript expertise. 

Following these are Java, C++, and C#. These highly effective object-oriented languages are often taught at school and broadly used within the office. Applications written in these languages may be simpler to arrange and keep, so many groups use them to construct large-scale methods—Netflix, Uber, and NASA’s Mars Rovers all have necessary providers written in Java. These languages even have domain-specific makes use of: Java is used for Android apps, and C# is usually used for Microsoft’s .NET platform or recreation improvement. 

MySQL is a relational database administration system (see this article for a fast clarification of what which means), used to retrieve and course of information. Throughout the area of interest of data-related assessments, MySQL is a well-liked alternative. NoSQL databases like MongoDB or Redis have additionally change into common for constructing merchandise, however MySQL stays a precious talent as many groups nonetheless depend on relational databases.

TypeScript is a extra highly effective extension of JavaScript. In comparison with JavaScript, TypeScript is object-oriented and has quite a lot of modifications to make it extra versatile. Although it’s not as common as another decisions, it’s nicely suited to a variety of initiatives. 

Swift is Apple’s proprietary language for constructing apps inside their ecosystem—most notably desktop and cellular apps. It’s generally utilized in assessments of a candidate’s iOS improvement expertise.

Providing the Proper Choices to Candidates

For sure duties, there’s a transparent set of instruments for the job. In these circumstances, you should use CodeSignal to judge a candidate’s expertise within the languages you want. As an example, in case you want an information analyst, you’ll be able to check a candidate’s MySQL proficiency by selecting from CodeSignal’s wealthy library of SQL duties.

When an evaluation is extra open-ended otherwise you’re testing for normal technical talent, take into account offering a wider vary of choices. It could sound apparent, however the extra common languages are those candidates need to use most frequently. If it’s cheap, give candidates a language-agnostic evaluation utilizing a framework-based Tech Screen or Pre-Screen, or allow them to decide the language they’d like to make use of within the digital onsite interview. You’ll be capable to higher assess their expertise in a language they’re comfy with, and also you’ll give your self entry to extra candidates.

Although some programming languages go out and in of style, those on this record are long-lived. We anticipate candidates will proceed to make use of them for a very long time to come back. The place related, take into account providing these choices to candidates to allow them to shine. If you happen to’re serious about utilizing CodeSignal to judge your candidates’ technical expertise, in no matter language, join our free demo.
