These are just a small sample from our library of 15,000+ questions. The actual questions on this Golang Online Test will be non-googleable.

🧐 Question
Medium Defer, Panic, and Recover Control Flow Error Handling	Solve
Consider the following Go code snippet, where we're exploring the use of defer, panic, and recover: In this pseudo-code, badCall function is deliberately causing a panic. test function uses a deferred function to handle the panic and recover from it. What will the output of this code be when it is run?
Medium Go Maps Maps	Solve
Which of the following statements are true regarding the order of output for following Go code: A. Output will be ordered by values B. Output will be ordered by keys C. Output will be ordered randomly D. Output will be ordered by position in the code
Medium File Handling and Defer File Handling	Solve
Consider the following Go code. Where should we use defer?
Easy Go WaitGroup Concurrency	Solve
What does the following Go code output?
Medium Mutex Locks Mutex Goroutines Concurrency	Solve
Consider the following Go program: What is the expected output of the final counter when the program is run?
Easy Registration Queue Logic Queues	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Test candidates on core Go/Golang Hiring Test topics

Go Fundamentals: Go Fundamentals is the foundation of programming in the Go language. It covers the basics of syntax, variables, data types, and control structures, enabling developers to write efficient and reliable code.

Variables and Types: Variables and Types in Go are crucial for understanding and manipulating data. They provide a way to store values and specify their type, allowing developers to perform calculations, data transformations, and comparisons.

Functions and Methods: Functions and Methods are essential concepts in Go for modularizing code and achieving reusability. They encapsulate a set of instructions or operations to perform a task, enhancing code readability and making it easier to maintain and debug.

Control Flow: Control Flow refers to how the execution of a program is managed based on specified conditions. It includes if-else statements, loops, and switch statements, which enable developers to control the flow of execution and make decisions based on different situations.

Arrays and Slices: Arrays and Slices provide ways to organize and manipulate collections of data in Go. They offer efficient storage and retrieval of elements, as well as capabilities for sorting, searching, and modifying data structures.

Structs and Interfaces: Structs and Interfaces are fundamental concepts for representing complex data structures and defining contracts in Go. Structs provide a way to group related data fields, while interfaces define a set of methods that a type must implement, enabling polymorphic behavior and code reuse.

Concurrency and Channels: Concurrency and Channels are vital for writing concurrent and parallel programs in Go. They allow multiple tasks to be executed concurrently, communicating and synchronizing through channels, enabling efficient resource utilization and improving overall performance.

Error Handling and Testing: Error Handling and Testing are essential for writing robust and reliable Go code. It involves techniques to handle and propagate errors, ensuring proper program execution, along with writing tests to validate the functionality of code and catch any potential issues.

Packages and Libraries: Packages and Libraries in Go provide modularization and code reuse. They allow developers to organize code into separate units of functionality, improving code maintainability and facilitating collaboration with other developers by providing a standard way to share code and dependencies.

File Handling: File Handling in Go involves reading, writing, and manipulating files. It allows developers to work with file systems, perform operations such as opening, closing, creating, and deleting files, as well as reading from and writing to files, enabling data storage and retrieval.

JSON and Web Services: JSON and Web Services are essential for building and consuming web APIs in Go. JSON is a standard data format for exchanging information between systems, while web services allow communication over the internet, enabling developers to create and interact with APIs, retrieve and manipulate data from external sources.

Database Connectivity: Database Connectivity in Go involves establishing connections, querying, and manipulating databases. It enables developers to interact with a database management system, perform operations such as creating, reading, updating, and deleting data, integrating Go applications with databases to store and retrieve data efficiently.
