Companies employ Data Scientists to analyze and interpret complex digital data to get insights that assist in making better-informed business decisions. It’s a multiskill job where a statistician, a computer scientist, and a trend-spotter are combined into one human being. This human being stands one foot in the business and the other foot in the IT world. Regarding the intellectual and educational capacity that the Data Scientist position requires, it’s quite a heavy lift. However, even if you stop in the midway of learning the craft, you’ll have a bunch of skills that you can use in many different contexts — no loss in any way.

The specific roles and duties vary in each organization, but typically, the main things Data Scientists do are these:

  • Collecting large amounts of unstructured data and turning it to be more usable.
  • Solving business problems with data-driven techniques.
  • Developing data analysis algorithms with R, Python, SAS languages, for example.
  • Working on statistical tests, distributions, and drawing insights from big data.
  • Communicating and working together with colleagues from business and IT sides.
  • Visualizing insights so that non-IT business people could understand what data presents.

In today’s world, it’s all about the skills rather than university diplomas. We agree that having a Bachelor’s and Master’s degree will set you up for a start, but how many years will it take to graduate? 4-5-6 in total, depending on the country? That seems like a lot of years! These days, you can take shortcuts more effectively than ever before. Make a structured learning path and get skills in 9 major areas that are essential to an aspiring data scientist: statistics, linear algebra, general development/coding, query database, business analytics, data visualization, soft skills, data engineering, machine learning. Online courses are flexible in time and your ability to choose only what you need to learn, so you’ll end up saving much time that you can use for practice. Employers are happy with talents who have had hands-on experience, so choose your priorities wisely.

Like mentioned earlier, if you go down the traditional way – and there are reasons to do that – you’ll get the degree in 3 to 6 years, hopefully, getting enough opportunities to practice. Or you can choose only selected online courses, spend more time practicing, and you should be able to get the basic skills in under 18 months to be able to apply for junior positions. To become an expert, having the multidisciplinary nature of a data scientist’s work, it’s pretty much a lifelong learning case. Experienced data scientists in the US, Europe, and Asia report that 5 years is the average time it takes to become a good data scientist with knowledge and practical skills.

Typically, Data Scientist’s salary will depend on your experience and where your employer is located. It varies from an average annual salary of around $46,000 in the Netherlands to as much as $120,000 in the US. In the US market, the difference between an entry level Data Scientist and a senior specialist can be quite significant, $69,000 and $162,000 respectively. In Europe, those differences are smaller, and the average European Data Scientist earns around $53,500 per year.

With a healthy amount of patience, you need to prepare very well for the job. Not just the technical stuff, but also get ready to be a part of an organization where you’ll deal with colleagues. Before even applying for a position, have your portfolio ready (you might want to post your projects on GitHub). Develop a genuine interest in what Data Science professionals really do on a daily basis to get a better idea of what the job involves. Also, don’t forget that when somebody invites you for an interview, it means they need you as much as you need a job, so relax a bit and bring your best!
