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 15,000+ questions. The actual questions on this .NET Online Test will be non-googleable.

Medium AppDomain Resource Scoping Configuration Management AppDomain 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: 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.
Medium IDisposable Pattern Garbage Collection IDisposable Pattern Memory Management	Solve
Consider the following .NET C# code snippet implementing IDisposable pattern: 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.
Medium Remoting and Object Lifetime .NET Remoting Object Lifetime MarshalByRefObject	Solve
In a .NET application, you are using .NET Remoting to communicate between different application domains. You have the following server-side code: 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 Sorting By Custom Order	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 String Parsing Character Counting	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.

.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.

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.

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.
