About the Exploratory data analysis test

Exploratory Data Analysis (EDA) requires a balance of creativity, cleverness, and deep knowledge of statistical analysis. An expert EDA practitioner must also quickly learn and internalize the nuances and needs of varying industries and businesses. This hiring test focuses on feature engineering, data visualization, and statistical analyses to identify candidates who excel at intermediate EDA.

A strong exploratory data analyst converts business problems to data science problems and uses data and visualizations to create and test solution-driven hypotheses. This screening test presents example datasets across industries and asks candidates to choose actions to solve issues and respond to questions typical for EDA practitioners.

This Exploratory Data Analysis (EDA) test assesses a candidate’s ability to work with data from start to finish. This screening test evaluates a candidate's ability to extract key information, develop various kinds of data visualizations to identify trends, as well as understand and interpret various kinds of data types.

Candidates who perform well on this screening test will have a strong understanding of EDA and a practical ability to perform various kinds of data analysis. This is an intermediate test designed for someone with 2-3 years experience with EDA.

VP of engineering, mid-market (51-1000 FTE)

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

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.
