About the Pandas test

Pandas is a Python library for data analysis, built on top of two core Python libraries: Matplotlib for data visualization and NumPy for mathematical operations. From data pipelines to data analysis to data cleaning, Pandas is an integral library for any Python developer working with data. A candidate proficient in Pandas can help you produce clean, efficient code that is more easily understood and maintained than most proprietary solutions.

This Pandas test for Python programmers assesses candidates’ knowledge and skills around the core functionality of Pandas. Using questions that focus on both library knowledge and practical uses, it evaluates candidates’ skills in the areas of cleaning and indexing data, basic data manipulation, combining multiple data objects, and data aggregation.

Candidates who perform well on this test have a strong grasp of Pandas and practical experience using the library. They know how to manipulate data for specific purposes, and how to prepare data for analysis. The test ensures that candidates have all the technical skills needed to meet your company’s goals for data manipulation in a clean, efficient way.

Review from G2

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.

What is an online Pandas test? How will it help you?

An online Pandas test is a pre-employment skills assessment that helps you evaluate your candidates’ ability to use the Pandas library in Python in a faster and bias-free manner. Pandas is a library written for Python and used for data analysis. It’s actually built on top of two other libraries: NumPy for mathematical functions and Matplotlib for data visualization.

You can use the online Pandas test to make sure that you hire a candidate who has the skills needed to operate the Pandas library. You’re looking for candidates who score well on the test since this proves they have expertise in Panda’s functionalities.

Finding, attracting, and hiring the right candidate is becoming harder than ever. The competition for candidates, especially software developers, is fierce. Moreover, many companies encounter hiring problems in the recruitment process that interfere with their ability to make the right hire:

Limited suitable talent: In all likelihood, you’ll receive plenty of applications for your open position. The problem is that many of your applicants won’t be qualified for roles that require Pandas skills. This means you’ll have to go through hundreds of applications to find a couple of candidates who might have the right Pandas skills.

Unconscious bias: Even once you’ve gone through all of the applications you’ve received and shortlisted some candidates, you won’t know if the list is a result of unconscious biases in the hiring process. You can fall victim to biases even if you’re well aware of how they can impact your decision-making.

Overreliance on resumes: The last obstacle to hiring the most suitable applicants is an overreliance on resumes in the hiring process. When you screen resumes, you’re not actually assessing candidates’ proficiency with Pandas but rather their CV-writing skills.

So what’s the solution to all these challenges? Simple: pre-employment tests.

How the Pandas test evaluates candidates’ skills

The Pandas test will solve multiple problems in your hiring process. It enables you to assess candidates’ actual Pandas skills and knowledge instead of their ability to write convincing CVs.

The Pandas test lasts 10 minutes and is meant for software developers with intermediate-level Python skills. The test evaluates whether candidates have the following Pandas skills:

IndexingBasic data manipulationCombining multiple data objectsData aggregation

Remember to look for candidates who ace the Pandas test. Applicants who do well on the test understand Python and how to use the NumPy and Matplotlib libraries. You can rest assured that they have the necessary skills to use Pandas effectively in your workplace.

This skills test is essential if you’re looking to hire candidates for any of the following roles: data analysts, data engineers, data scientists, machine learning engineers, machine learning scientists, Python engineers, and any role that requires candidates to have Pandas expertise.

The results of the Pandas test provide you with the data you need to make informed hiring decisions. This will completely eliminate bias from the hiring process so that you can feel confident you picked the right candidate.

The benefits of using the online Pandas test

You can solve many problems in your hiring process by using the Pandas pre-employment test:

Quickly evaluate hundreds of applicants: You’ll no longer be swamped by hundreds of CVs that you’ll need to sift through to find a few qualified candidates. Instead, you’ll save loads of time by implementing pre-employment tests in the hiring process. All of your applicants will get the opportunity to show their skills by taking the Pandas skills test. All you need to do is distribute the test to all of them with a single click and wait for the results.

Remove hiring bias. When you use a skills test like the Pandas test, you’ll eliminate bias from the hiring process. There’ll be no need to worry about whether your candidate shortlist is the product of unconscious bias. Instead, you can evaluate candidates based solely on their test results and pick those who performed the best.

End your reliance on CVs: CV screening is an outdated way of assessing candidates in the hiring process. It’s prone to multiple hiring biases and evaluates candidates’ CV-writing skills instead of their actual proficiency in Pandas. You can replace CVs entirely with a pre-employment test and assess applicants for the skills you need.
