Did you know that the unemployment rate for data scientists is negative! That is because there are more data science jobs than qualified data scientists in the job market.

Data Science has been considered one of the most lucrative areas in the technology industry in recent years. Harvard Business Review had gone one-step ahead in 2012 and called ‘data scientist’ as one of “the sexiest jobs in the 21st century.” Looking ahead at the future of data science, one can applaud the foresight of that tagline.

We are in the middle of the 4th Industrial Revolution (Industry 4.0), which is mostly being driven by Data Science. This ever-growing field involves the collection, analysis, and exchange of data, lots of data! The demand for professionals for various data science jobs is at an all-time high, so is the gap in supply. BLS suggests that professionals with backgrounds in biology, finance, and computer science will have incredibly powerful leverage to grow in a career in data science.

Data science is not an easy field, and you need to be very persistent to be successful in this field. Avoid thinking of Data Science as magic, where all problems can be solved using data-driven methodologies. Be aware of what data science jobs entail; don’t be swayed by what you see or read. So to help you answer your question – How to become a data scientist – let’s focus on the basics first, and know what is the entire fuss about data science!

What is Data Science?

Data science is a multidisciplinary field where a blend of data inference, algorithm development, and technology is used to solve analytical problems or provide insights on data. Data science can be generally divided into two groups:

Data insights – One of the main aspects of data science is to uncover findings from the gathered data. Data is as important as the person who is dealing with it. One must know how to dive into the data and find as much information from it in order to be useful.

Data products – It can be anything from software to any technical asset, which processes the data to provide meaningful information, helping form informed business decisions. Data scientists play an important role in building these data products and providing a platform where one can easily analyze the right data to get the right output.

How to become a data scientist?

One does not become a data scientist overnight. It takes a lot of learning, experience, and understanding of the concepts. Before you travel on your career journey to become a data scientist, there are some questions that you need to ask yourself:

Do you love numbers, figures, and graphs? Data science is all about numbers and figures. If you don’t like playing with numbers, you will find it frustrating later in your career.

Can you program without difficulties? Data scientists should be comfortable with various programming languages like R, Python, etc.

Are you willing to learn and start at an entry-level before reaching a proper data scientist role? If you are someone who has no experience in data analysis, you may have to start in an entry-level position.

When you have a positive answer to the above questions, you can go ahead and start acquiring the skills associated with data science. Let me share some infallible tips that can help you make a career in data science.

 

1. Make Sure Data Science is for You

As mentioned above, data science is no play, and you must be very persistent to be successful in this field. Bear in mind that you can’t solve all the data-related issues with just a magic wand. Data science is a deep and vast domain and requires extensive knowledge and a specific skill set to excel. Understand different job roles in the field. A data analyst is different from a data architect, while a data scientist’s role is different from that of a data engineer.

2. Build Your Own Projects & Portfolio

Employers won’t pay you to do something you’ve never done before. If you are currently working, try to apply everything you are learning in your work. On the contrary, if you are not working, start developing your own projects that involve all the new data science tools you know.

You should have around five projects that are relevant to the job role of a data scientist, such as data cleaning projects that include data preparation, data, munging, and data cleaning, data storytelling, and visualization project, group projects, etc.

3. Showcase Your Projects and Their Results

Start displaying the value your projects added to your workplace. If you are not employed anywhere, showcase your projects and their impact on a personal blog, GitHub, a video on YouTube, Twitter, or any other digital medium that helps you to make your skills go viral. Show your bosses and acquaintances what you have learned and strikingly communicate your results through graphs and data visualizations.

 

4. Gain Some Professional Experience

Before starting a career in data science, you must gain relevant experience, as data science jobs require a high level of mathematical and statistical knowledge and maturity. You would be able to effectively apply these sophisticated techniques only after you have gained relevant work experience.

 

5. Develop a Professional Online Presence

Update your LinkedIn profile, share your projects, engage with similar profiles to maintain an excellent online presence or upload tutorials to YouTube. You can also write blogs sharing your experiences and give your opinion on current issues in the field of data analysis (for example, new technologies, new algorithms, etc.).

6. Master the Skills

You need to acquire the right knowledge of data analytics tools, technologies, and programming languages to practice data science skillfully. A 2018 Kaggle study reveals that Python, SQL, and R are the most popular programming languages that a skilled data scientist must learn. Apart from these, you must have an impeccable command over –

  • SQL and NoSQL databases
  • Relational algebra
  • Parallel databases
  • Parallel query processing
  • Scala
  • Java
  • SQL (Structured Query Language)
  • Data Visualization
  • Machine learning
  • Statistical modelling
  • Experimental design
  • Bayesian inference
  • Decision trees
  • Data optimization
  • Storytelling
  • High-quality visual representation
  • R packages domain like ggplot2
  • Ability to modulate the data into actionable decisions
  • Graphical display tools

How will certification or professional training in data science help?

A majority of data scientists are from science, math, or statistics background, having a master’s degree or a Ph.D.  However, to think that a master’s degree or a Ph.D. is mandatory is a misconception. One can become a data scientist without having a master’s degree or a Ph.D.

Professional training always helps and you can enjoy many benefits from it. It is great to have the above-mentioned skills. However, if you are someone who has no experience or have just started your career in data science, a certification can surely help you. It will help you to get better job prospects and improve your salary.

 

9. Stay up-to-date with the Data Scientist community 

You should have saved some of the Data Scientist community pages to your bookmarks, keep visiting these websites to find out what’s going on, and you can also get information on the type of data science jobs they offer.

 

10. Practice!

So the question would arise, how do you practice data science before you have a job in the field?

Well, you can practice on projects from open-source data, participate in contests like HackerEarth and HackerRank, etc., volunteer or intern. The best data scientists will have project experience and an unseen benefit that will give them a better chance of being hired by companies.

 

11. Acquire the desired non-technical skills

Communication skills – Data scientists should have good communication skills to translate their technical findings to other non-technical teams or stakeholders. This way you can help non-technical teams like marketing and sales to understand your findings, with the help of which they can make informed business decisions.

Business understanding – Data scientists should have a good understanding of the business to find the right information from the gathered data. Also, their data wrangling and interpretation activities should be aligned with the business goals of an organization.
