Explore the Data Scientist Career Path

Data scientists collect, organize, and analyze large sets of data, providing analysis that is key to decision making. Governments, non-profits, and businesses of all types rely on data for forecasting, risk management, and resource allocation. Data scientists discover and analyze trends in data, and report their findings to stakeholders. They will use algorithms and models to simplify and mine data sets to create data-driven recommendations. Data scientists are needed across a handful of industries, especially the ubiquity of data and the reliance on it for business decision-making.

The Day-to-Day as a Data Scientist

Data Scientists interpret the results of data that they’ve processed, modeled, and analyzed to create actionable plans for their employers. With such broad opportunities, the day-to-day life of each Data Scientist varies. Data Scientists might be cleaning data, collecting data, analyzing data, creating data visualizations, making predictions, researching, risk modeling, or testing hypotheses. These skills contribute to things like reports, predictions, risk assessments, product or service improvement, and more.

Data Scientists can work in many industries including retail, tech, medicine, and government agencies. Most Data Scientists work on a team to make data understandable to those who need to use it to inform their decisions, create reports, or assess risks. They work full-time, usually, in onsite or remote positions. They can find part-time and freelance work as well.

What Skills Should Data Scientists Have?

Data Scientists should have strong analytical and communication skills. They must be proficient in SQL, Python and R, file management, machine learning and algorithms, natural language processing, linear algebra, calculus, statistics, and probability. Most jobs will also require proficiency in data modeling and visualization tools like Tableau. Data Scientists will need to be team players, good at pattern recognition, detail-oriented, and passionate problem-solvers.

It is essential for Data Scientists to dial in their soft skills. These skills will depend on the employment environment. Some Data Scientists work for large organizations where they will have to communicate their findings to upper-level management and C-level positions, others work with doctors and writers to create reports, some work for startups and will communicate directly to a team of founders, while still others will find themselves communicating directly with a small group of clients. These communications will essentially be educating the person(s) receiving the analyzed data.

Typical Qualifications to Become a Data Scientist

You do not need a higher education degree to become a Data Scientist but many Data Scientists have a bachelor’s degree in mathematics or data science. Some also have graduate degrees or certifications. Many employers will require at least a four-year degree for this position. Typically, it is more important for a Data Scientist to demonstrate skill proficiency and thought processes than to have a degree.

Certifications are available for Data Scientists both from the Data Science Council of America (DSCA) and various vendors such as Microsoft, Google, IBM, Cloudera, and Dell. These certifications may boost a Data Scientist’s chances of employment but they are not required.

Tips to Become a Data Scientist

Data Scientists who are consistent in their job search should be able to find a job somewhat swiftly but will need to pass rigorous technical interviews. Along with a polished résumé, a Data Scientist should have a well-rounded portfolio that showcases their thought processes and technical knowledge. Case studies that use real-world data manipulated into reports with visualizations, predictions, and inferences alongside the thought processes that lead you there are ideal for showcasing skills in this field. Posting these portfolio examples on a cleanly designed blog is common practice so that potential employers can view your work.

Data Scientists should also be utilizing LinkedIn to its fullest potential. Your LinkedIn profile should be up-to-date, include all past experience, and include keywords relating to Data Scientists’ skills and responsibilities. It should also show and tell how your past experiences offer transferable value to your position as a Data Scientist.

To get a leg up, try to connect with a point person at each company you send an application to, whether you applied via LinkedIn or not. Add a letter of introduction as a note with your connection request that includes a conversation starter. This will provide you with name recognition and sometimes first-hand advice. You should also make these connections with people who might be your manager at any company you would like to work for regardless of whether they have posted any job openings.
