How to Hire a Data Scientist

Data scientists are growing in demand across the world in a wide range of industries, ranging from healthcare and automotive to science and research. Organizations are continuously collecting and generating data—and data scientists help us analyze and make sense of it. While many companies have entire teams of data scientists in-house, not many can afford to hire full-time data scientists. Smaller organizations usually hire a freelance data scientist or consult experts on an on-demand basis.

Who is a Data Scientist?

A data scientist is simply someone who helps you make sense of data or generates value from data.

For example, a data scientist could help build a predictive model for the sales of a product, by identifying a pattern based on existing data. A data scientist could also work with machine learning algorithms to deliver personalized recommendations, develop  AI-based tools for automation, or perform a statistical analysis of laboratory research results.

Hiring a Data Scientist: Job Description

While hiring a data scientist on Kolabtree, it is essential to develop a job description that clearly defines:

Hiring a Data Scientist: Skills to Look For 

The primary thing to look for in a data scientist is their education and work experience. Most data scientists nowadays have a Masters degree, if not a PhD. The 2018 Burtch Works report mentions that education plays a huge role in determining data scientist salaries, with data scientists holding a PhD earning higher median base salaries than those holding a Master’s degree in every job category.

On Kolabtree, most data scientists are specialized with a PhD or a Masters in a particular subject or discipline such as machine learning or AI. Many of them have interdisciplinary experience — meaning they could specialize in data science within biotechnology or business analytics. When you’re hiring data scientists, you don’t have to necessarily look only for those with a qualification in data science. Astronomers, physicists and biostatisticians also work with large amounts of data and may have the expertise necessary for your project. You could also have a look at the ‘Publications’ section of the freelancer’s Kolabtree profile to see a list of their published work in journals and books.

Data scientists work with a variety of programming languages, most popularly R and Python. If you have a preference for a tool or program like SPSS/STATA, Hadoop or Tableau, discuss previous projects the freelancer may have worked on using these tools.

Hiring a Data Scientist: Interview Questions 

While each interview will depend on the project at hand or the challenge you’re looking to solve, here’s are three main things to keep in mind which will help you select the best-suited candidate.
