One evening, I was catching up with a friend over a few drinks – let’s call him Jon (name changed). He seemed determined to become a data scientist and was charting out his career plan accordingly.
I quizzed him around his awareness of what a data scientist does and sniffed that he wasn’t sure. So I threw this puzzle to him:
There are 4 people A, B, C and D, each with one of the these designations: A Data Scientist, A Data Engineer, A Data Analyst and a Data Architect. I also had job descriptions of their roles, which I passed on to Jon. He had to match the description to the right designation.
To penalize him for his errors, he had to take an alcohol shot for every wrong match he did. Can you guess the number of shots he took that evening? How many would you end up taking, if you were in this situation?
I would just say that he was lucky that I didn’t throw this puzzle at him with all the 8 designations I had JDs of that evening.
While the demand for various data science roles is increasing by the day, people in industry have used the designations and descriptions a bit loosely. Hence, there is a lot of confusion around who does what in the industry!
We hope this infographic “The Data Science Industry: Who Does What designed by DataCamp” helps you to find out ideal job role. We have provided a brief description of these roles and an infographic for you to take away.
If you have any questions related to designations and roles, feel free to ask them through comments below. I will be as helpful as my time can permit. Enjoy!
Description of various data science roles:
The Data Scientist
Data Scientist is most likely one of the most sizzling job titles that you can have these days, and with a yearly average salary of $118,70, they are amongst the top earners in the data science industry.

The title of statistician is regularly overlooked by or replaced by fancier sounding job titles. This is a bit of a pity, given that the statistician, with his solid foundation in statistical theories and methodologies, can be seen as the pioneer of the data science field. It is often he who reaps the information from the data and transforms it into actionable insights. To end, although the title can sound a bit dull compared to the others in this list, modern statisticians are always ready to rapidly ace new advancements and utilize these to benefit their research.

However, the business analyst compensates for this lack of technical knowhow with a profound understanding of the various business processes that are in place. A business analyst therefore often performs the role of the middle person between the business folks and the techies. Organizations searching for business analysts are companies like Uber, Dell and Oracle.
Data and Analytics Manager

This individual consolidates strong and specialized skills in a various arrangement of advancements (SQL, R, SAS, … ) with the social aptitudes required to deal with a group.
