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.

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.

Test candidates on core C# & .NET Hiring Test topics

C# Syntax Basics: C# Syntax Basics refers to the fundamental rules and structure of the C# programming language. It includes concepts such as data types, variables, operators, control structures, and methods. This skill is important to measure because a solid grasp of syntax basics ensures that candidates can write clean and error-free code, helping them build a strong foundation for more complex programming tasks.

C# OOPs: C# OOPs stands for Object-Oriented Programming in C#. It involves concepts such as classes, objects, inheritance, polymorphism, and encapsulation. Assessing this skill is crucial as it demonstrates a candidate's ability to design and implement well-organized, reusable, and maintainable code using object-oriented principles.

C# Data structures: C# Data structures encompass various ways of organizing and storing data efficiently, such as arrays, lists, stacks, queues, dictionaries, and linked lists. Evaluating this skill is important because it assesses a candidate's understanding of choosing and implementing the appropriate data structures for performing operations efficiently and managing memory effectively.

.NET MVC: .NET MVC (Model-View-Controller) is a software architectural pattern used in .NET framework for developing web applications. It separates the application logic into three interconnected components: models for data management, views for data presentation, and controllers for handling user interactions. This skill should be measured to gauge the candidate's familiarity with building scalable, modular, and maintainable web applications using the MVC pattern.

.NET API Development: .NET API Development involves creating APIs (Application Programming Interfaces) that allow different software systems to communicate and share data. This skill is worth evaluating as it demonstrates a candidate's expertise in building robust and secure APIs that enable seamless integration between diverse systems and enable third-party developers to access and utilize their functionalities.

C# Programming: C# Programming encompasses the broader set of programming concepts, techniques, and best practices specific to the C# language. It includes topics such as exception handling, file I/O, multithreading, LINQ, and generics. Measuring this skill helps assess a candidate's proficiency in utilizing advanced C# features and applying them effectively to solve complex programming challenges.

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.

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.

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.

What is the cost of using this test?
