About the Test

This test assesses applicants’ understanding of and proficiency with Conditional Statements, Loops, Arithmetic Operators, Object Oriented Programming with Arrays and Strings.

C# is a general-purpose, multi-paradigm programming language. C# encompasses static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented, and component-oriented programming disciplines.
With our C# test, you can hire C# Developers, Software Engineers, Software Developers, and Software Architects.

C# is known for its simplicity, expressiveness, and flexibility, making it a popular choice for developers of all skill levels. It is often used in conjunction with the .NET framework, which provides a rich set of libraries and tools for building a wide range of applications. C# is also compatible with other platforms and technologies, including Windows, Linux, and iOS, and it can be used with a variety of development environments, including Visual Studio and Visual Studio Code.

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 C# Programming

Working with C# programming involves using the C# language and related tools and libraries to write and maintain code for various types of applications. This may include writing and debugging code, testing code, and collaborating with other team members on software development projects.

2

Serialization

Serialization in C# refers to the process of converting an object or data structure into a format that can be stored or transmitted over a network. This can be useful for storing data or transferring data between systems or applications.

3

Asynchronous Programming

Asynchronous programming in C# involves writing code that can perform tasks concurrently or in parallel, rather than sequentially. This can help to improve the performance and responsiveness of applications by allowing them to perform multiple tasks at the same time.

4

Abstract Class

An abstract class in C# is a class that cannot be instantiated and is intended to be used as a base class for other classes. Abstract classes can contain both abstract methods (methods without a body that must be implemented by derived classes) and concrete methods (methods with a body that can be used directly).

5

Delegates and Events

Delegates and events are C# programming concepts that allow you to write code that can be executed in response to specific events or conditions. A delegate is a type that represents a method, and an event is a mechanism for subscribing to and unsubscribing from a delegate. Events are often used in C# to enable communication.

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 C#

1. What is the difference between value types and reference types in C#?
Why this Matters?

C# has two types of data types: value types and reference types. Understanding the difference between these types is essential for efficient memory usage and avoiding common programming errors.

What to listen for?

Listen for the candidate to explain the key differences between value types and reference types, how they are stored in memory, and how to use them correctly.

2. What is a delegate in C# and how is it used?
Why this Matters?

Delegates are a powerful feature in C# that enable event-driven programming and provide a way to encapsulate and pass methods as parameters.

What to listen for?

The candidate should be able to define a delegate, explain how to create and use them, and understand the difference between a delegate and an event.

3. What is LINQ and how is it used in C#?
Why this Matters?

LINQ (Language Integrated Query) is a powerful tool in C# for querying data sources, such as arrays, collections, and databases.

What to listen for?

The candidate should be able to explain what LINQ is, how it is used, and provide examples of how to write LINQ queries in C#.

4. What is a lambda expression in C# and how is it used?
Why this Matters?

Lambda expressions are a concise way to write anonymous functions in C# and are often used in conjunction with LINQ and delegates.

What to listen for?

The candidate should be able to define a lambda expression, explain how it is used, and provide examples of how to write and use lambda expressions in C#.

5. What is a generic type in C# and how is it used?
Why this Matters?

Generics provide a way to write reusable code in C# by allowing methods, classes, and structures to work with different data types.

What to listen for?

Listen for the candidate to provide a clear explanation of what a generic type is, how it is used, and provide examples of how to write and use generic types in C#. Additionally, the candidate should be able to explain the benefits of using generics in C#.
