Hire Golang Developers

Golang, also known as "Go," is a statically typed, compiled, and open-source programming language designed by Google. It is similar in syntax to C, but with memory safety, garbage collection, structural typing, and concurrency in the CSP paradigm. Although its official name is Go, it is frequently referred to as Golang due to its previous domain name,

A Go/Golang developer is a highly skilled individual with the capacity to translate software requirements into high-performance products and provide analytical solutions to a range of problems. Working with Go and utilizing its whole set of tools and frameworks is among the fundamental responsibilities of a Golang programmer. Debugging and testing are other common tasks for Go developers.

Due to its simplicity, readability, efficiency, and concurrent nature, Go quickly gained popularity and became the preferred language among many developers. It can perform numerous tasks simultaneously if they are concurrent. Go is used for cloud-based programming, game development, data science, and server-side (backend) programming. Making command-line tools is another common use for it.

Due to its popularity and rising demand, hiring dedicated Golang developers can be a tedious process, which is why it is important that you know how to hire Golang developers effectively.

What to look for when hiring Golang Developers

Although recruiting Golang experts may seem straightforward, there are a few things to look out for if you want to hire a Golang developer and get the finest candidates for the job that will help your company succeed.

Technical skills

Look for developers who have a wealth of experience, the technical know-how necessary to succeed in the position you are hiring for, and the ability to collaborate well with your current development teams.

Golang developers should possess a broad range of technical abilities. If you wish to hire dedicated Golang developers, they should have expertise in backend development, web development, mobile development, and software development. First and foremost, the ideal Golang developer needs to be well-versed in the Go programming language, paradigms, techniques, and idioms. 

They must also possess in-depth knowledge of all Go frameworks and tools, including but not limited to dependency management tools like Godep, Sltr, etc., Go's code generation tools like Stringer, and well-known Go web frameworks like Revel. 

They must also have extensive knowledge of common Goroutine and channel patterns. They ought to be knowledgeable about code versioning tools as well (such as Git, SVN, and Mercurial). Note that the developer you hire need not possess all of these abilities and credentials—although they are crucial—but a solid understanding of them is acceptable.

Communication skills

A Golang developer needs to be proficient in speaking and listening, in addition to having the appropriate technical knowledge and work experience. The ideal developer must be able to communicate well in order to create a committed development team and forge seamless relationships with both the team and other staff members at the companies they work for.

Software development is frequently a collaborative process, finding Golang experts with strong communication abilities can help you maintain a pleasant working environment.

Familiarity with the Go channel frameworks and patterns

Concurrent goroutines exchange information and communicate with one another using Go channels. Due to this approach, any data passing via two goroutines are exchanged in synchrony.

When many threads need to share data concurrently, this data is "locked" in many other programming languages. All kinds of memory management problems result from this.

Go solves this issue by passing the value of that data variable between threads using Go channels while both threads 'wait' for the value to arrive at its destination. Without the hassles brought on by locking variables, this "waiting" ensures thread synchronization.

The producer-consumer queues, condition variables, and other widely used concurrency frameworks may all be implemented using the various Go channels (both buffered and unbuffered), which the best Golang developers should be extremely familiar with.

Knowledge about cloud computing

Finding top Golang developers with cloud computing knowledge is essential if you want to build cloud-based applications. They must have a solid understanding of at least one well-known cloud service like Amazon Web Services, Microsoft Azure, Google Cloud Platform, and IBM Cloud.

Godoc commenting

Every language has tools for discussing and documenting code-related information. Go is no different. Godoc searches the whole Go source code for any comments and then assembles them to create the package's documentation automatically in HTML or plain text. 

The ability to quickly switch between a function's description and implementation using the Godoc web interface, for example, makes it simple to create user documentation that is closely related to the relevant code. 

Go developers should be aware of the formatting standards that Godoc uses when converting comments to HTML, how comments are parsed by Godoc (for instance, containing comments at the package level but excluding comments at lower levels), and how to write clear and useful Godoc comments.

Top 5 Golang Developer Interview Questions

Channels or maps, which would you choose for concurrent data access?

Asking this question to a developer would allow you to “pick” at their intelligence and know just how technically sound and vast they are. Only those who are truly experienced would be able to provide the right answer. 

It would be wiser to select channels over maps because it is the more secure alternative. When we have more threads, the block and lock mechanisms in channels prevent goroutines from exchanging or leaking information.

In contrast, the aforementioned lock/block functionalities are absent from maps. If information needs to be protected when using maps, unique or specific locking mechanisms would need to be used to secure any information and data moving through the goroutines.

What are the functions that can stop or suspend the execution of an ongoing Go routine?

This might seem like an easy question, but an experienced Go developer must have good knowledge of not just the “advanced” questions but the basics. The current Go routine can be stopped or suspended using one of four functions:

  • running time.Gosched: As it joins the queue and surrenders a CPU core, this is automatically carried out.
  • runtime.gopark: Until the callback function unlocks in the parameter list and returns false, the Go Routine is blocked.
  • runtime.notesleep: The thread will be hibernated by this function.
  • runtime.Goexit: This will immediately halt the execution of the goroutine and call defer, but it won't elicit a panic response.

Is Go capable of performing inheritance?

This is a tricky question and one that would allow you to assess the knowledge level of the developer. 

The correct answer here is “no, not really,” as Golang does not support classes and does not provide inheritance functionality. Examine the developer's response to the topic to see if they have any suggestions for using pre-existing struct objects to define the initial behavior of new objects while simulating inheritance behavior with composition.

When does the Go runtime allocate memory from the heap and when from the stack?

A developer who can answer this question demonstrates extensive knowledge of the Go runtime and is a good indication of their skill. When programmers execute their instructions, memory is allocated from the heap. A heap is a collection of memory that programmers can allocate and free up.

The data members of a stack are temporary memory allocations that can only be accessed while the method() that included them is active. As soon as the associated method completes execution, the memory is automatically allocated or released. We experience the corresponding Java.lang.error. If the stack memory is entirely occupied, the JVM will throw a StackOverflowError.

How are working environments and parameters configured?

This question is perfect for letting you vet the experience and knowledge level of the developer. The right developer must know the proper way to configure environments and parameters. 

JSON can be utilized to set up operating conditions and parameters. The fact that JSON is included in the standard library is its main benefit. The standard library provides writing methods for the intended data structure, which makes it very readable. The YAML package for Go is an additional choice.

How do Go interfaces work?

Demonstrating in-depth knowledge of Go interfaces should provide a good indication of one's level of skill. Go's interfaces are distinct from those of other programming languages. A set of one or more method signatures can be specified using a new type called a Go interface. 

The word "type," the name, and the keyword interface are used to form the interface. The definition of the interfaces is:

  1. A set of methods
  2. Type

Common questions about hiring Golang developers

Yes, there is a shortage of Golang developers. Although the demand for Golang developers is constantly on the rise, there isn’t enough supply of people with these skills to meet the demand.

Yes, Golang has a future. Since its birth and introduction into the technical world, Golang has continued to rise in popularity, and its developers are constantly in demand. Top businesses worldwide use Golang, and concurrency is also very well supported by default in Go, which is one of the reasons for this. It is also simple to spin up tens of thousands of "goroutines." As a result, it ranks among the top languages for concurrent programming.

Also, given that Go compiles at breakneck speeds, this language has a very "dynamic" sense to it. Go uses garbage collection and static typing. Go is also a very simple programming language with just a few basic notions (like goroutines, interfaces, maps, and slices). It is quite simple, which makes it easy to learn and master. For real software engineering, this is essential.

The following are some of the main job responsibilities of a Golang developer, though specific duties will vary from one Go developer to the next depending on the business, the project specifications, and their position's requirements.

  • Using Go to create apps that are efficient, scalable, and optimized
  • Investigating and fixing problems to improve performance.
  • Making applications connect to other web services and creating and developing back-end components.
  • Looking at new technological developments to continuously improve the functioning
  • Provide technical documents, code documentation, and other input.
  • Becoming a part of code reviews.
A lot of top companies use the Golang programming language. Some of them include Dropbox, Uber, Trivago, SoundCloud, Twitch, Medium, and American Express.
