Part 2: Developing the expertise you need to get a job in data science
Data science is a constantly evolving field that requires hands-on experience to master. While formal education and theoretical knowledge are important, practical experience in data science is crucial to becoming a successful data scientist. In this section, we will discuss whether a university degree is required to secure a job in data science and some ways to gain practical experience.
Is a university degree necessary for a career in data science?
With the increasing reliance on data for decision-making, the demand for data scientists has skyrocketed in recent years. However, the question of whether a university degree is necessary for a career in data science remains a topic of debate.
While some employers may require a degree, many are more interested in a candidate's skills and experience in the field. Those who have taken online courses, attended bootcamps, or completed self-study programs may have acquired the same skills as those with a degree in a related field. For example, Constructor Academy’s 12-week data science bootcamp
can provide the required knowledge to become a data scientist.
Moreover, many successful data scientists come from diverse educational backgrounds, such as computer science, mathematics, engineering, and statistics, which have equipped them with the necessary skills for a career in data science. Thus, a university degree may not be an absolute requirement for securing a job in data science.
However, some employers may still require a university degree, especially for more senior data science positions. Also, a degree may be necessary for those who want to specialize in a particular area of data science, such as machine learning or data engineering. Furthermore, having a degree in a related field may give candidates an edge over others, demonstrating a deeper understanding of data science’s foundational concepts and theories.
Therefore, while a university degree may not be essential for entry-level data science positions, it can be a valuable asset for those wanting to advance their careers.
