Integrate our Data Analyst test to hire expert talent

How well do your candidates perform exploratory data analysis (EDA) tasks, and which professional applicant should you hire for your open position? Because hiring EDA roles are complex and hiring an expert requires you to evaluate several skills, it can be tricky to determine which professionals are most suitable for your organization’s needs. The best way to make this decision more easily is by using this Data Analyst test. Our subject-matter experts made the Data Analyst test to ensure you hire top talent regardless of the challenges.

You might have already noticed that traditional hiring techniques have not produced the recruitment results you're looking for, failing to find the right EDA expert for your team. Don’t fret. This Data Analyst test will help you identify genuine professionals far more efficiently than poring over dozens of CVs.

The most skilled EDA experts can transform complex business problems into data science, representing those issues as valuable data and visualizations. There are multiple benefits to having a capable and professional EDA professional on your side, one of which is to test data-driven hypotheses and solve problems efficiently.

Nonetheless, if you’re a recruiter without any EDA expertise, you may find it challenging to hire an EDA applicant. If you have a large talent pool, filtering exploratory data analyst candidates takes longer than expected. If you’re an HR professional using traditional resume screenings, optimizing your time and dedicating due attention to onboarding and training is difficult. Alternatively, our EDA test enables you to speed up the hiring process, assess your candidates objectively, and identify the most suitable candidates far more effectively than traditional hiring methods.

FAQs

What is the difference between an assessment and a test?
An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.
Can I add my own questions to an assessment?
Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.
How do video questions work?
A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now." You can learn more about video questions here.
Can you explain how the other custom question types work?
Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
Can I customize an assessment with my company logo and color theme?
Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.
