How a DevSkiller Data analysis test works

The RealLifeTesting™ methodology is behind each Data analysis test that DevSkiller produces. It allows recruiters to analyze an applicant’s knowledge of Data analysis and for candidates to show off their coding ability, problem-solving and time-management skills. Previously used algorithm tests fail in their ability to really demonstrate a developer’s skillset, but a DevSkiller Data analysis test can offer you an in-depth view of a candidate’s attributes, all from the initial screening stage.

What to look for in a Data analysis engineer

The idea behind Data analysis is to extract useful information and make decisions based upon that data. Effectively it is the process of cleaning, transforming, and modeling data to discover useful information to help when making business decisions.

To simplify it, think of it like an event in real life. If you are planning for a certain outcome or you are remembering what happened last time to affect your future choices, then you are effectively analyzing the data available and basing your decisions upon that data.

Data analysis engineers use specific tools to help process and manipulate data and look at patterns and correlations between different data sets.

There are several ways data can be analyzed including Statistical analysis, Descriptive analysis, Diagnostic analysis and Predictive analysis.

To hire a Data analysis expert you have to think about what kind of data they will be analyzing for your business and this will help to work out what kind of Data analysis field they should specialize in.

A DevSkiller Data analysis test will be able to help you work out who the real experts are within your candidate group and narrow down your search for the right Data analysis engineer for your business.

Want proof that a Data analysis test will really work?

It is a sensible approach to not be completely swept off your feet on first hearing about our screening tool. After all, you need to think about your company’s finances. We think the following customer testimonial might help to persuade you though:

Clevertech

Started in 2000, Clevertech uses creative problem-solving to help the world’s most innovative organizations build game-changing technology.

The issues facing Clevertech were the sheer amount of applications their recruiters had to sift through. They also found that interviews were a great way to gauge a person’s fit for the company, but not accurate at measuring technical ability. It was a slow process and not the most efficient.

Clevertech’s own developers now use DevSkiller’s customizable tests, to create a unique technical screening challenge for their applicants. The challenge is tailored to focus on the areas most important to Clevertech. By implementing DevSkiller into their pre-existing recruitment process, Clevertech has managed to cut down on interviews, speed up their entire recruitment process and make higher-quality hires than in previous years.

“DevSkiller tests have given candidates the opportunity to prove their technical ability quickly in the interview process. Before, we used to have to book out back to back days of interviews to ensure we were hiring a quality candidate. However, with this integration, we are now able to hire higher-quality candidates with fewer interviews.”

Hayden Trumbo – Recruiting Coordinator at Clevertech
