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 Ado.Net Test will be non-googleable.

🧐 Question
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.

Why you should use Pre-employment Ado.Net Online Test?

The Ado.Net Test offers a focused method for evaluating a candidate's proficiency in .NET data access technologies. It provides a practical approach to gauge real-world skills as opposed to purely theoretical knowledge, ensuring that candidates who excel are equipped with applicable capabilities.

This test's questions are designed to assess a range of practical skills required for working with data in .NET applications. It gauges understanding of core ADO.NET concepts, data access patterns, and database connectivity techniques. Expect evaluation of the ability to manipulate data using ADO.NET objects, bind data to UI controls, and utilize different data providers. Questions also explore knowledge of disconnected data access approaches and handling ADO.NET transactions, as well as familiarity with Entity Framework and LINQ to SQL for data querying and manipulation.

Upon completion, you'll receive a detailed scorecard for each candidate, highlighting their strengths and areas for improvement. This report includes a skill-by-skill breakdown of their performance, enabling you to quickly identify top candidates who possess the data access skills your team needs. Use this data to inform your hiring decisions and streamline your recruitment process.

What topics are covered in the Ado.Net Online Test?

This test gauges a candidate's ability to work with data using ADO.NET and related technologies. It covers a spectrum of data-related skills, starting with core ADO.NET concepts, ensuring they understand the architecture for data access in .NET applications. This competency is key to building applications that interact with databases.

Furthermore, the assessment evaluates Data Access methodologies and Database Connectivity, revealing how well candidates can retrieve and manage data from various sources. Competence here is critical for any application that relies on data storage and retrieval.

The test also measures Data Manipulation skills, focusing on the ability to modify and transform data within a database. This includes understanding how to execute queries to update, insert, and delete records. Being proficient in Data Binding and usage of Data Controls is checked too, ensuring candidates can create dynamic user interfaces that reflect changes in the data. These are important when building user-facing applications.

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.

I just moved to a paid plan. How can I request a custom assessment?
