If you are a developer in the tech industry, being up-to-date with the most popular programming languages can be essential for career success. In fact, many IT roles now come with the expectation that you have a certain level of understanding of the most common and useful programming languages, even if you are not a computer developer!
With the ever-changing job market, knowing which coding languages to master can put you ahead of the competition. In this blog we take a look at 5 in-demand programming languages in the tech industry- based on online research as well as our own client, candidate and vacancy data. We also provide some tips on how to upskill, prepare for interviews, and why programming languages are so essential.

In-demand Programming Languages: our top 5
Java is one of the most popular object-oriented programming languages and is designed to support multi-operating system applications on mobile devices, laptops and desktops. It is a great language to learn for developing modern apps. One of the main reasons why Java is so widely used, is due to its scalability and flexibility, allowing developers to create high-end applications. If you are looking to get started with Java, here are some useful links on getting started:
Python is a general-purpose programming language commonly used for web development and artificial intelligence (AI) engineering. It is the most prevalent and popular coding language in the world and used in many large organisations, such as Google, Instagram, Spotify, Dropbox, and X (formerly known as Twitter). Python is popular because it is concise and easy to read, allowing developers to get a project running quickly. To get started with Python, here are some useful links:
C++ is an object-oriented programming language used to develop software, applications, and drivers. One of the biggest reasons developers choose C++ is because it is a low-level language allowing for faster computations, allowing for apps to run even faster. C++ is commonly used in applications that require high performance and video games. If you are looking to get started with this language, here are some useful links:
JavaScript is another popular programming language used to build application user interfaces (UIs) and websites. JavaScript is "the language of the web", and almost every website uses it in some way. JavaScript has been around since the early days of the world wide web and is used for both animations and web page interactivity. It is also necessary for single page applications, which continuously change content without a page refresh. To get started with JavaScript, here are some great resources:
C# is an object-oriented language developed by Microsoft. It is understood by both Windows applications and mobile applications. It has many of the same features of modern languages such as Java, providing the flexibility and scalability applications need. It is also used to build Windows and Web applications, two of the the most popular types of applications. Here are some resources to get started with C#:
With so many free resources available for developers today, upskilling is more accessible than ever. One of the best ways to learn new programming languages is through online courses. Platforms like Coursera, edX, and Udacity provide complete courses on coding and development, and best of all, are often free and offer certification upon completion. When starting to learn a new language, always hit the ground running as mastering concepts in the early stages will help in the long run!
Another great tool for upping your coding knowledge further is cheat sheets, which cover similar topics to those mentioned in courses, such as syntax and keywords. Once you have a basic understanding of the language, explore tutorials that cover the more illegal and practical aspects of creating something with the language. Finding relevant newsletters and dedicated websites or social media accounts is another great way to stay up to date with the latest coding trends, ultimately ensuring that you remain in the know.
When applying for roles in the development field, it is important to be well prepared for the interview process. This often begins with researching the language you will be tested in. More often than not developers will be tested in coding, problem solving, whiteboarding, algorithm based tasks, and theory, so it is essential to cover these topics in depth. Another great way to prepare is to use online testing platforms, like Codility, for practice.
It is also important to ensure you have your current CV, and relevant portfolio work, ready. Having a portfolio is something that can help you to provide your knowledge to potential employers. For whiteboarding sessions, you should be confident enough to explain your thought process, and to have examples of code ready to show to the interviewer during the test.
A career as a developer can be incredibly interesting and rewarding. We understand how competitive the job market is and strive to help our candidates to find their perfect roles. Whether you are a graduate, at a junior level or already established in your career, our team can match you with the perfect role for your skill-set, so you can start your journey to tech success.
