Go is a statically typed programming language, open-source, compiled, efficient, readable, and high-performing.
It was created by Google to simplify the search engine’s codebases back in 2012.
Its popularity has continued ever since due to the features of running multiple tasks simultaneously, efficiency and simplicity.
Stats about Go
There are numerous surveys showing the popularity of Go from various aspects, starting from usage, brand names using Go, salaries, demand and more.
For example, some of the big brand names that use Go are Uber, PayPal, Meta, Bitly, Netflix, Dropbox, and many others.
Regarding the demand of Go developers, their precise vocational titles and salaries, as well as job openings, specifically in the USA, a full-stack developer with experience in Go, earns a salary of $101.959 per year, and for this position, there are fewer than 1868 job openings. Another example, a DevOps engineer with Go expertise, the estimated salary would be $118.395, and there are 1459 job openings, according to the stats.
But, in this context, regarding top paying technologies rank, Go is at 9th ranked place, with a $75.669 annual salary.
When it comes to choosing Go as the preferred language for programming, a hefty number of 10.000+ JavaScrip developers would choose either Go or Rust for their work. But, also, 14.54% of developers said they would want to work with Go.
Interviewing a Go developer
Helpful tips for a pre-screening interview
During the interview with the Go developer, a hiring specialist pays attention to several things to conduct the proper interview questions and get valuable information.
The interview specialist asks general questions to get to know the candidate and focuses on soft skills. They will also focus on checking their English proficiency, communicativeness, and responsiveness.
Top technical skills to look for in a Go developer
A great Go developer needs to understand the responsibilities assigned to them, such as:
- Creating and writing testable, scalable, efficient, robust codes that are easy to maintain
- Having the central deciding role in the design and architectural issues
- Translating all software requirements for the end goal of functioning, secure, and stable software of high-performance
Further, we asked senior Go & Java backend developer Diego Maia about critical technical skills in a Go (Golang) developer, to which he listed:
“Paying attention to creating clean code and following the SOLID principle (Single responsibility, open-closed, Liskov substitution, interface segregation, dependency inversion).”
But there are other skills essential for a Go developer to have:
- Strong knowledge about Goroutine and all channel patterns
- Experience with constructs, paradigms, idioms about Go (Golang)
- Experience with Sltr and Godep (dependency management tools of Golang)
- Knowledge about the templating language of Golang
- Working with Stringer (Golang code generation tool)
- Experience with Gorilla Mux (router package)
- Experience with Revel (Golang web framework)
- Writing adequate and clean Godoc comments
- Knowledge about tools for code versioning, like SVN, Git, Mercurial
What distinguishes a great Go developer from a good one?
“A great Go developer needs to shine at working with error handling, pointers, and idiomatic Go codes,” added Maia.
Additionally, a great Golang developer will stand out if they have a variety of experiences and skills knowledge, such as PERL/Shell scripting.
Why and when do you need to hire a Go developer?
If you have a large project or complex workload especially, you need first to determine the preferred skills you expect of the developer.
How could you know when the right time to hire a Go developer for your project is? If your servers have to handle many requests with high traffic, this is one valid reason for complex workloads. Another reason is that it has an established business, so for heavy and challenging tasks and operations, Gol is good to go.
If your project or workload needs maximum functionality and speed, then you need a Go developer to maximize these factors in the long run.

Essentials and assessment of a Go developer
It is essential to know that the right candidate is communicative, responsive, has good English knowledge and proficiency, and has experience with Go.
An excellent example of assessment is assigning the developer the task of creating a small library. But also, a hiring specialist or expert in Go would ask about the following:
- Go packages and pointers
- Go string literals
- The syntax used for Go loops
- Go goroutines
- Go interfaces
- Type Assertion in Go
- Differences between GOPATH and GOROOT Go variables
Benefits of Go
Using Go comes with many benefits, and they all simplify the developer's work while also contributing to the fast and effective workflow in the long run.
As I already mentioned, Go is very fast, performant, and versatile, and it’s easily compiled to any hardware and all platforms. It can be a script language replacement and is highly conductive and fast.
Also, it is effortless to learn and implement in work (fit for newer and senior developers). In other words, upon the initial usage learning, the developer can start building things in just a few weeks of working with Go.
When asked about why he likes working in Go, Maia listed the following benefits:
- Strong standard library
- Good performance
- Easy to deploy
- Working with Terraform and Docker
However, the broad developer community also highlights the scalability, easy readability of code (like with Python and PEARL), and the numerous architecture benefits overall.
According to a Stack Overflow survey, Go is among the higher-ranked languages regarding how developers like it.

Why use Go?
Go is a compiled, concurrent, garbage-collected, statically typed language. It was developed and open-sourced in 2007 by Google. The Golang’s selling point is in the solid balance between speed, ease, and safety. Its biggest advantage over other languages is support for concurrency.
What is Go most similar to?
What is Go used for?
Go is first and foremost a cloud software language. It works well for building any server-side programs, such as pub/sub servers and clients, caching mechanisms, integration layers, and any services performing CPU or I/O intensive tasks. It suits for building any type of API using REST, GraphQL, or gRPC. Go also is good for DevOps tasks, such as writing update scripts, server maintenance software, or batch processing.
Who uses Go?
Go is widely used by companies dealing with cloud computing. Dropbox, Terraform, Docker, and Kubernetes were written in Go. Google itself uses Go for Google Cloud Platform, YouTube, Google Chrome download server, and a bunch of smaller projects to improve scalability and performance. You’ll find some well-known names, such as Heroku, SoundCloud, BBC, Basecamp, Bitly, among the adopters of this language.
Will Go replace any other programming languages?
Golang overlaps with and outperforms other languages to some extent. However, it doesn’t mean Go will force out any of them of the market. It rather will carve out some market share and find a niche for itself. The fact is that having realized Go’s superiority in solving scalability and concurrency problems, many companies migrated some of their APIs and microservices from Python, Node, C, or Scala to this language. But they didn’t remove the old languages from their stack completely.
Is Go faster than other programming languages?
If you consider benchmarks for programming language performance comparison, you’ll see that Go is slower than C/C++, somewhat equal to Java, and faster than any other language. Among the factors that slow Golang down, programmers usually mention imperfections of its garbage collection and memory management. Anyway, real-world apps written in Go are known for their fast speed and high performance, especially those that leverage concurrent programming.
Is Go a low-level programming language?
Although Go runs with the speed of low-level languages, it doesn’t really belong to them. The built-in support for garbage collection and memory safety differentiates Go from true low-level languages. Although Go has some low-level features (like pointers), it can’t be used as a system language and is not suitable for kernel development and writing drivers.
Is Golang better than Python?
At a first glance comparison, both Golang and Python have distinctive features. Golang offers incredible speed of performance with clear, strict formatting and syntax. On the other hand, Python is a more classic and standard language, slower than Golang, even though quite resourceful.
Powerful standard library with a set of library packages for a simpler code composure Simplicity through readability, maintainability, and reliability Web application building through easy constructs and good execution speed Offering channels and Goroutines a simple concurrency managing Compilation speed through parsability and no need for symbol table Testing support in a way that you can quickly test codes and packages you formulate
Easy coding through easy functioning learning Object-oriented programming through class concepts Public and free availability through simple clicking and downloading Interpreted high-level language that doesn’t require memorizing the architecture of a system Programming support for GUI (Graphical User Interface). Portable and extensible through easy formulating and compiling of the Python code into C and C++
Golang and Python are not too similar at first glance. Golang is an open-source, statically typed, and compiled programming language, with Google as its creator, and you can expect high-performance, readability, simplicity, and efficiency at all times. Python is a programming language used for building software and websites, conducting data analyses, and automated tasks and used to create various programs as a general-purpose language. The comparison result is that Golang is better than Python if you need more accessible and more straightforward system programming, speed, and support and finding experts working with it, even though Python shines in other segments.
Why use Golang?
Golang is easy to understand and use, so it is perfect for both novices and experts. Its simplicity goes hand in hand with the functionality, primarily if your foundation is in C or Java. With Golang, working is more practical and straightforward. Golang is easier to maintain than Java, with the same quality performance as C. Whenever you write a code in Golang, that code will adopt a format easily understood by the processor. Also, Golang will improve the services’ reliability and accessibility since it is way faster than other languages.
Another reason why Golang is great to use is that Goroutines need just 2KB memory. All essential functions will continue to run smoothly and fast, independently and with more than just one ongoing process simultaneously. When it comes to handling the development tools, with Golang, they are ready to use and in the form of IDE, plugins, or editors. Any developer would prefer working with the practical tools of Golang, such as GoMetaLinter for quick and easy code analysis or GoDoc for automatic document generating from a code. There is also a simple API for fast testing and a Race detector for preventing specific issues like race condition issues (when multiple threads try to change shared data simultaneously).
Is Golang still popular?
Golang is becoming more popular by the day. So far, Python and JS have both been increasing in popularity. Yet, still, even though Golang is relatively new, it was considered the most favorable, simple, and unbelievably easy to learn and use out of many. The numerous benefits of Golang make it a popular language to learn and use in programming. The rise of its fame is mainly due to its simplicity, which is often underrated, especially in tech-context. If something is easy to learn, use and implement, it speeds up the work process and contributes to efficiency. Another contextual and exciting fact about Golang’s popularity is that it uses just 25 keywords, all practical—all versatile. This static programming language has a simple syntax and is memory-managed, which are more reasons why it has become so favored. Golang is easy to pick up and use due to the simple and easy learning curve. Another valid reason for the popularity rise of Golang is that it is an excellent skill to have in a resume and usually goes along with a higher salary value, so there is a financial motivation, along with the personal expertise enhancement.
