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.

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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Apache NiFi 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.

What topics are covered in the Apache NiFi Online Test?

  • Apache NiFi

    Apache NiFi is a powerful and scalable data integration platform that allows users to design and automate data flows. It provides a visual interface for creating, managing, and monitoring data pipelines, making it easier to move and transform data between different systems.

  • Data Integration

    Data integration refers to the process of combining data from different sources and making it available in a unified format. It is important to measure this skill in the test to assess a candidate's ability to design and implement seamless data integration solutions using Apache NiFi.

  • Data Flow

    Data flow in the context of Apache NiFi refers to the movement of data from one system to another in a controlled and efficient manner. Measuring this skill helps recruiters evaluate a candidate's understanding of how data flows through the system and their proficiency in managing complex data pipelines.

  • Data Transformation

    Data transformation involves the conversion of data from one format or structure to another. This skill is crucial in the context of Apache NiFi as it enables users to manipulate and enrich data on-the-fly as it passes through the data pipelines. Measuring this skill helps identify candidates who can efficiently perform data transformations using Apache NiFi.

  • Data Routing

    Data routing refers to the process of directing data from one system to multiple destinations based on predefined rules or conditions. It is an important skill to measure in the test as it assesses a candidate's ability to design and implement efficient data routing strategies using Apache NiFi, ensuring data is delivered to the right systems or components.

  • Data Provenance

    Data provenance is the ability to track the origin, processing history, and transformations applied to data within a system. Measuring this skill helps recruiters evaluate a candidate's understanding of data lineage and their proficiency in leveraging Apache NiFi's data provenance capabilities for auditing, troubleshooting, and compliance purposes.

Apache NiFi 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.
