9 reasons why

Adaface Data Analysis Assessment Test is the most accurate way to shortlist Data Analysts

Reason #1

Tests for on-the-job skills

The Data Analysis 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 at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

Understanding the basics of data modelling including entities and relations
Applying data analysis techniques such as aggregations and statistics
Applying fundamentals of business analysis
Interpreting data using charts and graphs
Executing data queries and utilizing databases using SQL
Performing data operations including predictions and anomalies
Conducting data investigations including correlations and ranking
Utilizing popular data tools like Excel

Reason #2

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 #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Data Analysis 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.

Data Analysis Hiring Test FAQs

Can I use Data Analyst Test for hiring Data Scientists?

Yes, if your job description closely matches the data analyst requirements. You can also check our standard Data Scientist test for a more focused test.

Can I evaluate Python or R in the Data Analyst test?

Yes. You can have three variations of the test:

For Data Analyst (Python) roles: Along with the standard question set, the test will have Python MCQ questions and Python coding questions
For Data Analyst (R) roles: Along with the standard question set, the test will have R MCQ questions and R coding questions
For Data Analyst roles where candidates can know either Python or R: Along with the standard question set, candidates will be asked to pick their preferred programming language between Python and R. Then, the candidate will be asked the MCQ and coding questions on the chosen programming language.

To get a sense of what kind of questions will be asked to evaluate Python or R skills, you can review our standard Python Online Test and R Online Tests.

Can I evaluate Excel skills in the Data Analyst test?

Yes. Along with the standard question set, there will be scenario-based MCQ questions to evaluate on-the-job Microsoft Excel experience. You can review our standard Excel Online Test to see what questions will be used and what topics will be evaluated.

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.
