  • Machine learning: If your company uses high-tech machines, you need a data analyst with a basic understanding of machine learning. As AI tech is growing rapidly, data analysts should stay up to date on AI trends.
  • Data preparation: Data preparation involves transforming large raw data sets into organized and comprehensible reports. Data analysts require this skill to process all relevant data to include before creating visualizations.

How to hire data analysts

Below are five steps you can use to hire data analysts:

How to hire data analysts

1. Build a good candidate profile​

Finding top data analysts requires an understanding of the role. You can collaborate with the rest of the hiring team or a recruiter to discuss the ideal profile for the role. Take notes and use the results of this discussion to draft your candidate profile and requirements.

2. Write a skill-based job description

Once you determine the requirements for the position, you must also understand the relevant skills candidates need to succeed. You’ll want data analysts proficient in relevant tools like SQL, Python, and spreadsheet packages.

You can then prepare an extensive job description containing the role’s skills and requirements. The job description should also contain the job title, company overview, and remuneration.

3. Use a prescreening test

Pre-employment tests can help you identify and determine candidates’ abilities in specific areas. For instance, TestGorilla’s EDA test focuses on feature engineering, data visualization, and statistical analyses to assess data analysts with good EDA skills.

The pre-employment test presents sample datasets in different sectors and asks applicants to solve problems and answer questions relatable to exploratory data analysis. It’s an intermediate assessment for candidates with two or three years in EDA.

4. Interview exceptional candidates

After the pre-employment test, you’ll discover candidates who can effectively conduct several data-analysis operations. You can now use this result to shortlist candidates for the interview stage. Make sure to do some research into appropriate interview questions to guide the process.

5. Select the best candidate

After assessing soft skills and other traits in the interview stage, you can streamline your choices to a few candidates. You can now make special offers to exceptional candidates, containing bonuses and incentives to attract and retain them.

Recruiting candidates for data-driven roles

Hiring candidates for technical roles requires effective recruitment methods to assess candidates’ expertise and skills adequately. Reviewing resumes to hire candidates, especially for tech roles like data operations, can be unreliable.

Pre-employment tests are the new and most effective hiring models to assess candidates’ skill sets comprehensively. For instance, you can be sure candidates who perform well in TestGorilla’s EDA test have strong knowledge and skills in the area.

This hiring approach will help you identify the strongest candidates for data-related roles and similar fields, ensuring they have the skills to improve your company’s productivity.
