The .NET Online Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

  • Ability to effectively utilize .NET Framework in application development
  • Proficiency in C# programming language
  • Understanding and implementation of Web API
  • Knowledge of MVC (Model-View-Controller) architecture
  • Strong coding skills
  • Ability to work with databases in .NET applications
  • Knowledge of object-oriented programming principles
  • Experience with handling exceptions and errors
  • Understanding of .NET security and authentication
  • Knowledge of unit testing in .NET applications
  • Expertise in handling HTTP requests and responses
  • Familiarity with asynchronous programming in .NET
Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

These are just a small sample from our library of 10,000+ questions. The actual questions on this .NET Online Test will be non-googleable.

Resource Scoping
Solve
Consider a scenario where you have a .NET application that needs to load different configurations for different components running in separate AppDomains. You have the following code structure:
 image
The `ConfigManager` class is designed to load and store configurations for different domains. What will be the output of this program, assuming `ConfigA.xml` and `ConfigB.xml` contain distinct settings?
A: Config in DomainA: [Settings from ConfigA.xml], Config in DomainB: [Settings from ConfigB.xml]
B: Config in DomainA: null, Config in DomainB: null
C: Config in DomainA: [Settings from ConfigB.xml], Config in DomainB: [Settings from ConfigA.xml]
D: A runtime exception is thrown due to cross-domain operation.
E: Config in DomainA: [Settings from ConfigA.xml], Config in DomainB: [Settings from ConfigA.xml]
F: The output is unpredictable and depends on the runtime environment.

Memory Management
Solve
Consider the following .NET C# code snippet implementing IDisposable pattern:
 image
What is true about the garbage collection and resource management in this code?
A: The finalizer will always be called when the object is garbage collected.
B: The `Dispose` method is only called when explicitly invoked.
C: Managed resources will be freed in the finalizer.
D: Unmanaged resources are only freed if `Dispose` is called with `true`.
E: The `GC.SuppressFinalize` method prevents the finalizer from being called.
F: The `using` statement ensures that unmanaged resources are always freed.

Solve
In a .NET application, you are using .NET Remoting to communicate between different application domains. You have the following server-side code:
 image
This `RemoteObject` class is hosted in one application domain and accessed from another. Considering the lease settings (InitialLeaseTime, SponsorshipTimeout, RenewOnCallTime), what will happen if a client accesses the `GetData` method every 3 seconds?
A: The object will be disconnected after 5 seconds, regardless of the calls.
B: The lease will be renewed, and the object remains accessible as long as it's called every 3 seconds.
C: The object will be disconnected after 7 seconds, even with the regular calls.
D: An exception will be thrown due to lease timeout.
E: The lease will be renewed indefinitely without disconnection.
F: The object will be disconnected only if there is a call after 5 seconds but within 7 seconds.

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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment .NET Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the .NET Online Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

What topics are covered in the .NET Online Test?

  • .NET Framework

    The .NET Framework is a software framework developed by Microsoft that provides a programming model for building, deploying, and running applications. It includes a large library of pre-built code and supports multiple programming languages, allowing developers to build different types of applications such as desktop, web, and mobile. Measuring knowledge of the .NET Framework in this test is important to assess the candidate's ability to create robust and scalable applications using Microsoft technologies.

  • C# Programming

    C# is a modern, versatile programming language developed by Microsoft. It is widely used for building Windows desktop applications, web applications, and games. Understanding C# is crucial in this test as it allows recruiters to evaluate a candidate's ability to write clean and efficient code, handle memory management, and implement object-oriented programming principles.

  • Web API

    Web API is a framework provided by Microsoft that allows developers to build HTTP services that are consumed by various clients such as web browsers, mobile applications, and desktop applications. Testing knowledge of Web API in this assessment helps recruiters gauge a candidate's expertise in designing and implementing RESTful APIs, handling authentication and authorization, and working with data formats like JSON and XML.

  • MVC

    MVC (Model-View-Controller) is a design pattern commonly used in software development to separate the concerns of an application into three interconnected components. It provides a structured approach to building web applications, making them easier to maintain and modify. Including MVC in this test allows recruiters to assess a candidate's understanding of architectural patterns, routing, data binding, and handling user input in web development projects.

  • Coding

    Coding skills are the foundation of software development. This skill measures a candidate's ability to write clean, efficient, and maintainable code. It encompasses various aspects such as algorithms, data structures, problem-solving, and code optimization. Evaluating coding skills in this test allows recruiters to judge a candidate's proficiency in translating requirements into functional code and their ability to produce high-quality software solutions.

.NET Hiring Test FAQs

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

  • Non-googleable questions
  • IP proctoring
  • Screen proctoring
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser
  • Copy paste protection

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.
