About the Test

The Go test evaluates understanding of the Go programming language as well as the ability to use built-in functions to construct strong and maintainable code.

Go, also known as Golang, is a programming language developed by Google that is designed for building scalable, concurrent, and efficient software. It is known for its simplicity, speed, and ability to handle large-scale systems, and is used by many organizations for building web servers, cloud infrastructure, and other types of software.

Go has a simple and easy-to-learn syntax, and includes built-in support for concurrent programming and garbage collection. It also has a strong focus on performance, and is designed to be fast and efficient, particularly when it comes to handling large-scale systems. Go has a large standard library and supports cross-compilation, allowing you to build code for different platforms from a single machine.

Customer Satisfaction

Testlify helps you identify the best talent from anywhere in the world, with a seamless experience that candidates and hiring teams love every step of the way.

1

Working with function

Functions are blocks of code that can be defined and called by name in a Go program. Functions can take input arguments and return values, and can be used to organize and reuse code.

2

Error Handling

In Go, errors are represented by a special type called “error,” which is a interface that allows you to represent and handle errors in your code. Go provides several ways to handle errors, including the built-in “error” type, the “panic” and “recover” functions, and the use of return values to indicate errors.

3

Control statement

Control statements are used to control the flow of execution in a Go program. Go has several control statements, including “if” and “else” for branching, “for” for loops, “switch” for multiple branches, and “goto” for unconditional jumps.

4

Goroutine

Goroutines are a way to create concurrent tasks in Go. They are lightweight threads of execution that can be created and managed using the “go” keyword. Goroutines are used to allow multiple tasks to be run concurrently and are a key feature of Go’s support for concurrent programming.

5

Code

In the context of programming, code refers to the instructions and statements that are written in a programming language, such as Go. Code is used to specify the logic and behavior of a program, and is typically written in a text editor or integrated development environment (IDE).

The test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.

Top five hard skills interview questions for Go

1. Can you explain how Go’s garbage collection works and how it impacts performance?
Why this Matters?

Go’s garbage collector is a unique feature that sets it apart from other languages, and understanding how it works is important for writing efficient and high-performing code.

What to listen for?

Listen for the candidate’s ability to explain how Go’s garbage collection works and how it can impact performance. They should be able to discuss the different types of garbage collection and how to optimize code to work with it.

2. Can you write efficient concurrent code in Go using channels and goroutines?
Why this Matters?

Go is designed to make concurrent programming easier, and the ability to write efficient concurrent code is important for many applications.

What to listen for?

Listen for the candidate’s ability to use channels and goroutines to write concurrent code in Go that is efficient and scalable. They should be able to explain how to use these features and give examples of how they’ve used them in the past.

3. Can you describe how Go’s type system works and how it can be used to ensure code correctness?
Why this Matters?

Go’s type system is designed to help prevent common errors and ensure code correctness, and understanding how it works is important for writing reliable and bug-free code.

What to listen for?

Listen for the candidate’s ability to describe how Go’s type system works and how it can be used to ensure code correctness. They should be able to discuss how Go’s type system differs from other languages and give examples of how they’ve used it to catch errors.

4. Can you explain how Go’s interface system works and how it can be used to write flexible and extensible code?
Why this Matters?

Go’s interface system is a powerful feature that allows for flexibility and extensibility in code, and understanding how it works is important for building robust and adaptable applications.

What to listen for?

Listen for the candidate’s ability to explain how Go’s interface system works and how it can be used to write flexible and extensible code. They should be able to give examples of how they’ve used interfaces in the past and discuss the benefits and tradeoffs of using them.

5. Can you describe how Go’s memory model works and how it can be used to write safe and efficient code?
Why this Matters?

Go’s memory model is designed to provide a safe and efficient way of managing memory, and understanding how it works is important for writing code that is both safe and efficient.

What to listen for?

Listen for the candidate’s ability to describe how Go’s memory model works and how it can be used to write safe and efficient code. They should be able to discuss how memory allocation and deallocation works in Go, and give examples of how they’ve used this feature to write efficient and safe code.

Frequently Asked Questions for Go

A Go assessment assess an individual’s proficiency in the Go programming language, which is used to create scalable, concurrent, and efficient software.

A Go assessment is a tool that helps recruiters and hiring managers to assess candidates’ ability to write efficient, scalable, and maintainable code in Go. Candidates should also have a strong understanding of common Go routine and channel patterns.
