Hire Dedicated Golang Developers in 48 Hours

Go is an open-source compiled multi-threaded programming language developed by Google. Often it is also called “Golang” — short for “Google language.”

Go (Golang) is considered a general-purpose language, but its main use is the development of web services and client-server applications. According to GitHub, at the end of 2022, it was about to enter the top five in-demand languages, ahead of PHP, Ruby, and C#. Also, 11.15% of the expert developers surveyed by Stack Overflow said they are using this technology on a regular basis. 

The Go language is an attempt to adopt the best aspects of languages such as C++ and Java. There is only one question left: will your project benefit from Golang? Read on to see if the decision to hire Golang developer is right for you!

Golang Developers: Job Description

Golang developers can build robust and highly scalable applications and web pages. Furthermore, they test and debug existing IT products using the Go language.

But apart from the language itself, its syntax, and documentation, what does a Golang developer need to know?

Skills to Check Before You Hire Go Developers

To hire a Golang developer, you should check if the developer has most of the skills below:

• Strong knowledge of Go lang
• Javascript (with in-depth knowledge of one of the front-end frameworks: Vue, Angular, or React)
• HTML5 and CSS
• Experience with SQL and NoSQL databases such as PostgreSQL, Redis, MongoDB, RabbitMQ, and Kafka
• Understanding of containerization principles, experience with Docker and Kubernetes
• Experience in integrating with APIs of third-party web services
• Ability to write unit and integration tests
• Excellent knowledge of REST, HTTP, JSON
• Experience in high-load Golang projects, creating scalable solutions
• Knowledge of microservice architecture
• Ability to write scripts
• Knowledge of Git
• Some DevOps experience

These are technologies and frameworks which are most commonly used with Go lang.

Responsibilities of Golang Developers

Golang developers usually cover the following tasks:

• Building Go applications
• Improvement of Golang application performance
• Testing and debugging
• Code review
• Working with microservice architecture
• Working with the file system
• Development of multithreaded applications
• Writing SQL queries and their optimization
• Application of OOP principles and common design patterns
• Building RESTful APIs

The work includes a wide range of functionalities, but in simple words, Golang developers write code and maintain it to solve specific problems.

All Go Developers at Expert Remote At Least:

• Have mastered Go (Golang) core concepts (functions, structs, etc.). They are well aware that unlike in object-oriented languages like Java, the building blocks of Golang are types, functions, and packages. 
• Can manage program crushes/errors smoothly and skilfully. Our Golang developers mainly use debuggers like Delve and GDB. Delve supports Go runtime concepts and built-in types, while GDB is supported through the standard Go and Gccgo compilers.
• Reuse code with packages. Go is designed as a language that encourages good engineering practices. One of the industry practices that allow you to create high-quality software is code reuse, called DRY — “Don’t Repeat Yourself”. Expert Remote’s employees reuse code to save time and resources and reduce redundancy by using assets that have already been created in one form or another during the development of a software product.
• Leverage Goroutines to create powerful software. Goroutines are lighter and cheaper than threads, which means using them allows developers to create more flexible solutions.  
• Can write unit/functional/integration tests. Various types of tests ensure that the final result is optimized, works smoothly, and performs well. And there’re no bugs.
• Can create command-line programs. Command line programs help you to solve system administration tasks.
• Work with JSON REST APIs. The HTTP package in Golang makes it suitable for the effortless creation of REST APIs for client apps and data transfer. 
• Never stop improving. If you hire Golang developers from Expert Remote, you can be sure that our guys are polishing their skills every single day. None of our employees considers themselves a complete expert.

What Go Developers Can Build for You

If you own a startup or small business, Golang developers can help you out with the following products:

• Cloud-based (server-side) apps. With Go, developers can handle heavy requests on the server-side with little memory usage. Its high portability also makes it an excellent choice for cloud-based solutions.
• News outlets. With Go, you can build highly efficient news outlets, and this is possible thanks to its multithreading capacity that helps save CPU memory space.
• Distributed network services. Go’s focus on concurrency and API support, together with its static compiled language design, makes it excellent for developing distributed event-handling systems that can scale.
• Media platforms. Support for multi-threading by default makes it easy to write code and add advanced features to powerful applications like media platforms. To do this, the Go programming language has goroutines and channels.

These are the most common types of apps and services built on Go (Golang). So if you didn’t find your case in the list — feel free to contact our consultants.

Hiring Process of Golang Developers 

Usually, the hiring process consists of several stages:

• Identification of needs
• Determining the requirements for the position and the candidate
• Writing a job description
• Collection and sorting of responses
• Resume analysis
• Evaluation of candidates
• Final selection of candidates
• Testing (if necessary)
• Making an offer

It is advised to adjust this plan according to your business needs.

Interviewing Golang Developers

Evaluating the Hard Skills of Go Developers

Since the level of experience greatly impacts the role of an employee, we have to interview Golang developers according to their seniority levels.

Interview Questions for a Junior Golang Developer

Q: What do you like the most about Golang?

A:

• The language has a simple syntax and structure, making it easy for beginners to learn
• It compiles very quickly, which saves time and money
• It is platform-independent and works seamlessly on multiple platforms like Windows, Linux, etc
• It is parallel, and multiple processes can easily work together

Q: What do you hate the most about it?

A:

• There is no manual memory management tool that could cause garbage collection problems and pause the programming process
• Because the language is relatively new, many libraries are still not available to users
• Error handling in the language is inefficient
• Language safety at run time is not guaranteed

Interview Questions for a Middle Golang Developer

Q: What are structs in Go?

A: Structs are user-defined types that can group different types into one type. They are similar to classes in object-oriented languages.

Q: What is the Golang context?

A: A context is a package in Golang that is used to transfer requests, values, and signals across API boundaries to all necessary goroutines. 

Interview Questions for a Senior Golang Developer

Q: How do you get input from users in Golang?

A: To get user input in Golang, you can use three functions: Scan(), Scanln(), and Scanf() — depending on what you need to do with the input afterward.

Q: What kind of garbage collection does Golang use?

A: The Go garbage collector is based on a three-color label and a cleanup algorithm. This algorithm allows Go to be garbage collected during program execution and run at the same time. This reduces the chance of stopping while the program is running. If there are any problems with the scheduler, it can be configured to run garbage collection for short periods of time.
