There is more than one way to enter the data science field. Data scientist requirements differ by employer, industry, and location. Aspiring professionals can meet data scientist job requirements in various ways.
BACHELOR'S/INTERNSHIP
• Earn a bachelor's degree — Most data science jobs require at least a four-year bachelor's degree. Consider majoring in data science, computer science, or mathematics. Take classes in computer science, business, and statistics.
• Complete an internship — Getting internship experience develops career-relevant skills and can lead to job offers.
• Pursue professional certifications — Earning a professional certification is not required for becoming a data scientist, but it can help you prove your skills to potential employers.
• Get entry-level professional experience — Apply for jobs like data analyst, data engineer, and market research analyst. Spending several years developing your skills can lead to better job opportunities in the future.
BACHELOR'S/DATA SCIENCE BOOTCAMP
• Earn a bachelor's degree in any field.
• Complete a data science bootcamp — Data science bootcamps provide intensive career training in less time than most traditional college programs. You may need to complete prerequisites before starting a bootcamp.
• Pursue professional certifications.
• Get entry-level professional experience
ADDITIONAL TYPES OF DATA SCIENTIST
There are many other variations out there, and these will continue to evolve as data science becomes ever more prevalent. But while the list of job titles in data science may seem to be never-ending, there are 3 additional main categories that describe the different roles Data Scientists most commonly fill:
DATA ENGINEER
Data Engineers collect, store, and organize data. Job ads for Data Engineers will typically list a range of responsibilities, including the ability to source external data, build data warehouses, and design data models – three tasks that also build a foundation for data analytics and machine learning. Data Engineer is a relatively advanced professional position, and so typically requires a background in computer science, math, or engineering, as well as knowledge of SQL, Python, Java, or Ruby, and the ability to manage and design databases.
DATA ANALYST
Data Analysts use the data organized and made accessible by the work of a Data Engineer, turning it into insights that can solve problems, optimize products, and help make evidence-based decisions. Data Analysts can take complex information and turn it into stats that business execs can use to inform strategy and planning, often in the form of easy-to-understand data visualizations like charts and graphs.
MACHINE LEARNING ENGINEER
Machine Learning Engineers design software that can uncover insights and learn from results as more and more data is gathered. There’s quite a bit of overlap between Data Scientists and Machine Learning Engineers; both work with data to produce insights. The difference is that Data Scientists uncover insights to present to people (for example, CEOs and other business leaders), while Machine Learning Engineers design the tools that can discover insights and generate results.

Hello,
This is really good question and there's lots of great advice here! I had a very different route into data science and analytics than most - I studied music at university and then 'fell into' a data-related career path.
Interestingly, there are numerous similarities between the two fields, which highlight the essential skills beneficial to a career in data science. Abilities such as critical and analytical thinking, creativity, problem-solving, and communication are integral to both domains and have been instrumental in shaping my career. Additionally, my exposure to coding through activities like web-designing during my studies laid a solid foundation for understanding coding principles and visual communication.
A strong understanding of maths and statistics is crucial, but don't worry if you don't have a degree in these subjects - you can always develop these skills on the job. When I'm hiring, what stands out to me the most is a clear passion and aptitude for the subject, along with the ability to think critically, objectively, and articulate those thoughts clearly. While technical expertise is definitely a plus, it's something that can be acquired over time if you don't possess it already.
Hope this guidance proves useful,
Seb
