Recognized professional certifications

You might ask how to hire a Data Scientist with proven analytical skills among a myriad of specialists. Look for experts that have successfully passed one or more data science accreditations, such as Microsoft Certified Azure Data Scientist Associate, SAS Certified Data Curation Professional, and others. Professional certifications usually validate several data science skills at once. For instance, Certified Analytics Professional (CAP) accreditation covers a solid command of Machine Learning and algorithms for Data Science, probability and statistics, as well as exploratory data analysis and visualization.

Relevant domain knowledge

When setting up your engineering team, it is important to hire Data Science developers with experience in either your or a related industry. Your team members should have a basic understanding of how any engineering decision will impact the business. It is also more likely that when you hire Data Science developers in a similar domain will be able to translate the gained data insights and effectively present them to the client. 

Seniority level

The level of qualification of your Data Science developers is directly related to the quality of delivered services. Middle and Senior Data experts are more likely to have profound knowledge of the best industry practices and hands-on expertise in organizing unstructured data sets. 

Another aspect to pay attention to is the track record of your Data Scientists for hire. You might be sure that hiring specialists with more than three years of experience in research and analytics will guarantee a fruitful project outcome. 

For instance, at N-iX the average Middle Data Scientist has around four years of experience in the field, while Senior specialists—more than six.
