For some time now, companies have been collecting data on a large scale and analyzing it in a targeted manner to gain competitive advantages. However, many do not know how much work and jobs are needed to build and maintain such an infrastructure. That is why there is currently a big shortage of skilled workforce in the Data Science sector.
What skills do you need for Data Science Jobs?
The Data Science Jobs we will present throughout the article all have a common skill set that future applicants should bring to the table. These include:
Analytical knowledge is among the most important skills in the Big Data area. In order to be able to understand complex relationships, basic knowledge of mathematics and Data Science techniques is indispensable. One must understand which analytical tools may be used under which conditions and how to interpret them.
Data Visualization Skills
Any good analysis will be useless if you don’t manage to communicate the results as simply and understandably as possible to an audience that may be unfamiliar with the subject. This is most easily done by using nice visualizations.
An advantageous add-on for most employees with Data Science Jobs is basic programming skills in languages such as Python, C, or Java. In this field, one should have sufficient experience working with basic algorithms, data structures, and object-oriented programming. In addition, it is an advantage to be able to program quantitative and statistical analyses.
Problem Solving Skills
Working with Big Data poses problems, especially when working with unstructured data such as social media posts or images. In many cases, creativity and problem-solving skills are needed to find the best solution for the specific use case.
Structured Query Language
Despite the use of unstructured data and databases that are not based on the relational data model, the Structured Query Language (SQL) is still a cornerstone for querying data. Additionally, NoSQL approaches, such as Hadoop, still use SQL modules with which to query the data from the database.
Data Mining Knowledge
A key skill for aspiring Data Science Jobs is the use of data mining tools and algorithms.
The continued rise of Big Data applications is also leading to increasing demand for personnel who can handle such volumes of data. According to the 2018 LinkedIn Workforce Report, the U.S. alone has a shortage of more than 150,000 workers with data science skills.
