Who is a Data Scientist?
Data scientists are analytical experts skilled in technology and business science. First, they focus on gathering data for processing and extracting insights. Then, they use their analytical skills and business acumen to find feasible solutions to everyday business problems.
Naturally, the job demands robust analytical and critical thinking abilities. Therefore, math and statistics are the two core pillars of data science.
The roles and responsibilities of a data scientist include:
- Collect data from disparate sources, organize, and clean it.
- Preprocessing of raw data (both structured and unstructured).
- Analyze data using the latest analytical tools and techniques.
- Design advanced models to address modern-day business challenges
- Create predictive models and ML algorithms
- Use appropriate data visualization techniques to present their insights.
- Collaborate with data analysts, data engineers, and the BI team to ideate and develop innovative business strategies.
Skills required to become a data scientist
The job of a data scientist is highly analytical, and hence, the candidate must be skilled in calculations, algorithmic understanding, statistical interpretation, and analytical thinking.
Below are the qualifications that fit the description of a data scientist job:
- Should have a BA/BSc degree in Computer Science or Engineering
- Should have a data science diploma or certification
- Should earn a master’s degree in data science or a related field
- Ample experience in data mining and data visualization
- Should understand nuances of operations research and machine-learning
- Skilled in Python, R, SQL, Java, Scala, Python, and C++
- Proficiency in BI tools (like Tableau) and big data frameworks such as Hadoop
- Must have an analytical thinking approach and strong business acumen
- Highly skilled in math, probability, and statistics

Leading employers for the role of a data scientist
The IT, e-Commerce, healthcare, telecommunications, and banking & finance sectors are the leading employers for the job of data scientists. Companies in these fields often seek to efficiently understand their audience groups’ behaviour to focus on the best offerings and products catering to their customer needs.
Apart from these, the oil & gas and transport sectors are also increasingly capitalizing on big data to positively impact their employees, sales, operations, and target audience.
Some other departments that hire data scientists are:
- Government offices
- Research institutions and universities
With the relevant experience, one can even work for a consultancy these days. Consultancies offer more of a client-facing role, where you will work on projects for a cumulative range of businesses.
Working hours for a data scientist
Your daily working hours, the balance of work and personal life depends on the type of employer you work for. However, the core working hours are essentially a 10-hour shift ( for example, 10 am-6 pm, or 9 am-5 pm) for five days a week. Despite this, sometimes data scientists may need to work extra shifts beyond regular office hours if a project demands it.
Today, many organizations worldwide allow data scientists to work from remote locations in a more flexible work schedule.
