Isn’t it mind-blowing that around hundreds of programming languages exist in this world?
Several hundred programming languages exist in this world. But which of those are used by Google and will help you crack the Google interview? Depending on the function and range, several programming languages are used.
thecleverprogrammer To understand what programming language Google uses, it’s better to divide them into two categories — back-end and front-end. Learning these programming languages Google uses will help you not just land a job there but also perform well afterward.

As you start your Google interview prep, you’ll need to know which programming languages to prepare to crack the coding interviews. To help you out, in this article, we’ll cover:
What Programming Language Does Google Use? As one might expect, the programming language used at Google changes based on the requirement. When preparing for a Google interview, you should be aware of which programming languages are used in what projects at Google.
Programming Languages Used by Google for Front-end The front-end of Google has been kept pretty simple to provide a better user experience. It includes a search bar, an audio recorder, and the Google logo. The programming languages used here are:
1. JavaScript One of the most popular programming languages and considered the “language of the internet,” JavaScript plays a pivotal role in every web application. It supports the application by offering multiple features that convert it into a powerful platform.
The feature that lets Google users see suggestions while typing is backed by JavaScript. Gmail and Google Docs — are both created using this programming language. This helps Google to develop and open source its tools.
2. TypeScript A superset of JavaScript, TypeScript has been created and maintained by Microsoft to help develop large web platforms. At Google, TypeScript and Angular in TypeScript have been used to create popular products such as Google Analytics and the Google Cloud Platform.
The latter houses Google’s essential internal tools, such as product approvals, reviews, launch tools, etc. Therefore, the importance of TypeScript as a programming language for Google can’t be overstated.
Therefore, you need to be adept at JavaScript and TypeScript to run Google’s front-end operations.

Programming Languages Used by Google for Back-end Several algorithms and processes are running in the back-end of the Google Search Engine. Many programming languages are used to serve varying needs, whether indexing, crawling, or shortlisting the relevant search results. These are:
1. C++ It is one of the fastest programming languages used by Google primarily for ranking search results. Its other features (such as MapReduce and BigTable) can also be attributed to the programming language.
Apart from its speed, another great feature of this programming language is its portability, which means that it can be used on multiple devices simultaneously. It can also be used for other applications such as 3D graphics, GUI, etc.
2. Java An object-oriented programming language, Java is mainly used by Google for networking in the back-end. One of its most salient features is its versatility, as it can program both — operating systems and hardware devices.
Google also uses it for coding servers and creating the user interface.

3. Python The ideal language for beginners and seasoned programmers at Google, Python, helps carry out tasks that are deemed complex. Owing to its flexibility, it is perfect for data manipulation and management.
This is why this programming language is used for machine learning to get the best results and develop web crawler APIs.

4. Golang Similar to C, Golang is a programming language developed by Google to improve programming productivity. They wanted their programmers to be more efficient when coding and do more than that.
The programming language Google uses the vital features of other languages while dispensing their weaknesses. For example, it harnesses the efficiency of C++ while using the simplicity and productivity of Python.
5. PHP Created for web development, PHP is a scripting, general-purpose programming language. While many believe it is no longer used, Google and several other web platforms still use it to carry out their back-end operations.
Therefore, you need to deeply understand the programming languages such as C++, Java, Python, Golang, and PHP to run Google’s back-end operations.
6. Node Node.js is mainly used for non-blocking, event-driven servers because of its single-threaded nature as an open-source and cross-platform JavaScript runtime environment language.
At Google, it plays an important role in its back-end because it helps developers create high-performance applications and run on the web in a scalable manner by providing value to the users.
Take a look at some of the most popular back-end development languages to get a job at FAANG+ companies .
Google’s Programming Languages — Go and Carbon Aside from these popular Front-end and Back-end programming languages, Google uses its own developed languages to build large-scale products and services. Go, an open-source programming language was created in 2007, and Carbon, a recently launched language, was created to be a C++ successor. Let’s learn more about these two Google’s programming languages.
Go aka Golang As mentioned earlier in the article, Go is Google’s programming language built to develop efficient and reliable software. With built-in concurrency and a robust library, Go offers simplicity for software developers to create high-performing applications.
Mitrais Go has become one of the most popular programming languages because of its numerous applications. It can be used for a wide range of software development services, including Cloud and Network services, Command-line Interfaces, Web Development, DevOps & Site Reliability.
Carbon To make the transition from existing C++ codebases to Rust smoother, Google recently developed a new open-source programming language called Carbon. An experimental successor to C++, it has been created for companies and projects that are majorly dependent on the language.
However, Carbon is still a work in progress. Since C++ has been around for several years while Carbon is still in its experimental phase, it’ll be years before it can be used; not to forget, it’ll have to resolve the issues that C++ wasn’t able to.

As you can see, JavaScript is the most popular front-end programming language, whereas, for the back-end, it is Java and C++. And if you’re wondering about the difficulty level of these languages, read the hardest and easiest programming languages to learn for FAANG+ interviews .
Which Programming Language is Best for Getting into Google? While you’ll need to know only one programming language of your choice to clear the Google interview, the knowledge of these languages will only help you to advance your career in this tech giant. Python, C++, Go, and Java are the top programming languages used internally at Google.
As a tech giant, the company enables programmers to explore any programming language they like. So choose one or multiple, or just polish the language you already know, but make sure that it fits your needs and familiarize yourself with it.
What do experts say?
“You might not think that programmers are artists, but programming is an extremely creative profession. It’s logic-based creativity”.
