Adaface Entity Framework Online Test is the most accurate way to shortlist Entity Framework Developers



Reason #1

Tests for on-the-job skills

The Entity Framework 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.

The Adaface Entity Framework Online Test screens candidates for the typical skills recruiters look for .NET Developer roles:

  • Experience as a .NET Developer
  • Knowledge of .NET infrastructure
  • Proficiency in C#, F#, or VB.NET
  • Ability to use SQL or Oracle

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for .NET Developer roles. Anti-cheating features enable you to be comfortable with conducting assessments online. The Entity Framework Online Test is ideal for helping recruiters identify which candidates have the skills to do well on the job.

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.

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.

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

🧐 Question

Global Query Filters
Global Query Filters
Soft Delete
Solve
In an Entity Framework Core project, you're working on an e-commerce application where products can be 'soft deleted'. A soft deleted product is not physically removed from the database, but is flagged as deleted and should not appear in normal query results. Assume that your Product model includes an IsDeleted boolean property.

Your task is to implement a global query filter to exclude soft deleted products from all queries throughout the application.

Which of the following is the correct way to implement this requirement in your DbContext derived class, ProductContext?

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Entity Framework 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Entity Framework 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.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

FAQs

What is Entity Framework Assessment Test?

The Entity Framework assessment test is a pre-employment testing tool used by employers to assess a candidate's ability to work with the Entity Framework. It is a .NET Framework component that enables developers to work with data in an object-oriented way.

The assessment test focuses on questions around Entity Framework architecture, Entity Data Model (EDM), Entity SQL language, Object Services API & other fundamental topics to test for on-the-job skills.

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.

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
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser

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.

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