What to look for in Data Analysts

Data analysis is the process of cleaning, transforming, and modeling data to uncover important information to steer business decision making. It provides valuable insights that aid business growth and development. Python is one of the most popular programming languages in the world today. First released in 1991, it grew in popularity due to its simplicity and power. 

When verifying your Data analyst’s Python skills, it’s important to determine what (if any) commercial experience they have with the programming language. Additionally, it’s vital you garner an understanding of your candidate’s knowledge of the different Python libraries and why they are so important. Finally, uncovering your candidate’s knowledge of Python frameworks such as Django, Flask, Bottle, Tornado, or web2py, is essential in determining their suitability to the job role.    

Looking for something else?

Like the look of our Data Analysis with Python online tests but need something more? We’ve got you covered! With our online task wizard, you can create custom tests using your own codebase. These tests are fully customizable. You can choose the test length and scope, difficulty, and the types of questions i.e. academic questions, code gaps, etc. Finding your next Data Analyst with Python skills has never been easier with DevSkiller. 

Want proof our Data Analysis with Python tests actually work?

Making the decision on introducing a new tool to your company’s process is a big decision that shouldn’t be taken lightly. Listening to us is one thing, but if you really want to find out how our Data Analysis with Python tests work, then just listen to one of our satisfied customers:

Criteo:

Criteo is a global leader in commerce marketing. Their advertising solutions allow B2B companies to build personalized ad campaigns that target the right leads across retail, travel, financial services, automotive, and education. 

Every year Criteo has approximately 100 technical hires. Given the scale of their recruitment needs, Criteo needed a highly effective solution that can keep up with their rate of hire. They also required a standardized technical skills assessment process that can be used across their teams in 15 locations. 

Before implementing DevSkiller, Criteo used to send their technical candidates (excluding R&D), a case study to complete at home. This task was used first before conducting an interview with the team. Criteo faced many challenges including the impossibility of tracking the completion of the case study, limited insights into the validity of the results, but most importantly a delay in the hiring process due to wasted time and unnecessary interviews.

The solution? Implementing DevSkiller.

“We use DevSkiller in 15 locations around our 3 regions (US/APAC/ EMEA). We have 7 frequent users in TA (recruiters) across our regions and our technical hiring manager users rotate depending on current needs. More than 30 have logged into the platform once to review an assignment or create a test.” Julien Gauthiez – Talent Acquisition Manager EMEA at Criteo

Frequently asked questions

What is RealLifeTestingTM?

The RealLifeTestingTM methodology is the foundation of all DevSkiller Data Analysis with Python online tests. It goes beyond games and algorithm puzzles to provide a 360-degree view of a developer’s skills. At its core, The RealLifeTestingTM stems from the belief that the best way to evaluate a developer’s development skills is with a work sample test that mirrors the actual development work they’ll do. 

Our Data Analysis with Python tests require candidates to build full project apps or add features to existing apps, just like they’ll be doing after being hired. To do this they will need to show their knowledge of coding, in stack resources, resources like Stack Overflow to find solutions and decision making to find the best way to solve the problems they encounter. The results you see show the candidate’s coding skill, decision making, code cleanliness, and problem-solving skills.

How do candidates take a Data Analysis with Python test?

Devskiller’s Data Analysis with Python online tests can be taken from anywhere in the world. All the recruiter has to do is send the candidate a test invite. These invites can be set to be available for a specific amount of time. The candidates can then start the test whenever they want to for wherever they want to.  has the option of using our state of the art in-browser IDE or completing the project on their favorite IDE and then cloning the project to GIT. Throughout the test, candidates can run unit tests to make sure their solutions work the way they are supposed to. The test lasts for a set amount of time. At the end of the time limit, the test is automatically evaluated and the report is sent to the recruiter.
