As educators, there’s no greater pleasure than in helping our students find their way in data science. A few months ago, we sent out a survey to all of our community members, asking them about their concerns in beginning a data science career.
We received over 1,000 responses. On grouping them into common themes, the following questions emerged.
Launching a Data Science Career? Ask Yourself These Questions.
- Why do we need data science?
- What do I need to work in data science?
- How can I future-proof my job?
- When should I get started in data science?
I would have loved the opportunity to ask these questions at the outset of my career. I’ll offer my best hacks for getting your foot in the door, give you a ton of ideas as to where you can look for jobs, and show how you can start in data science with zero experience (it’s not as impossible as you may think!)
Why Do We Need Data Science?
I love answering this question – data scientists are always looking for answers to the “whys” of business.
To reach a conclusion, we need to understand what the field actually is. Data science encompasses everything to do with data. That may sound broad when you consider how ubiquitous data is, but that’s simply what it is.
Once upon a time, data science could only be found as a component within other fields. Over the years, these fields developed their own silos of algorithms, methodologies and communities that worked with data to answer business questions. But as data drives everything, it was only a matter of time that a discipline would emerge in its own right.
And emerge it has: The field has experienced serious growth, as we can see from this result of the search term “data science” on Google Trends:
Try it out for yourself. As with all great data science tools, you can filter your results (here, according to time, location, subject categories).
As the discipline can be applied to anywhere that has data, and as its principles add value, we can make a significant impact on the ways that businesses operate.
Why Do We Need Data Science?
- Because data is everywhere
- Because data adds value to businesses and people
What Do I Need to Work in Data Science?
As data science becomes more visible, many people have taken notice of the field, yet they remain mystified as to how they can access it. The good news is that the subject is so new that there is as yet no standard way to get into the industry.
Hadelin de Ponteves and I took different routes to becoming entrepreneurs in data science, so you may find you recognize yourself in one of our stories:
Hadelin de Ponteves
Hadelin began his data science journey in high school, when he developed a passion for mathematics. When it came to choosing a university degree, Hadelin naturally chose math. Upon completing his undergraduate degree, Hadelin decided that he wasn’t yet finished with the subject and so he studied for a master’s degree.
It was a logical move for Hadelin to then study at an engineering school in France. While there, he deepened his knowledge of a range of subjects, from mathematics to economics, biology and even philosophy, before specializing in machine learning (ML) and applied mathematics.
To strengthen his portfolio, Hadelin also took the opportunity to intern at French premium television cable channel, Canal+, where he learned the ropes in finance and strategy. Ultimately, what Hadelin wanted was to find somewhere he could both continue with his education and apply his theories to business.
Shortly after his studies Hadelin was snapped up by Google, where he worked as a data scientist for their business intelligence unit. Working at a massive conglomerate like Google gave him immeasurable experience in deep learning. But his goal had always been to be an entrepreneur and so Hadelin decided that it was time to start making online courses for the next generation of data scientists.
The true key to his success? Hadelin swears by a large bar of chocolate, once a day! Eating mountains of chocolate isn’t going to turn you into the next Hadelin, but our takeaway from this is to do what makes you feel happy and energized. The journey to data science requires dedication and skill; don’t forget to be kind to yourself on the way.

My story began the first time I sat down at a chess board. I loved chess, particularly the logic and strategy behind the game. It always took ages for me to make a move because I was obsessed with analyzing every eventuality possible for winning.
This early interest in logic was what drew me to physics at university. Although I enjoyed the subject, and it gave me some fundamentals I could apply elsewhere, I didn’t continue with it after college because it would restrict me to one field.
Additionally, I had always shown interest in business-oriented subjects so I undertook a master’s degree in accounting and finance. Both of these subjects were fundamental pieces to build up the confidence that entrepreneurship was possible.
Even so, I was cautious – I knew that to be successful I needed to see how other people did it. To acquire that knowledge, I applied for a job at Deloitte’s accounting department and was lucky enough to get the job. On my first day, a Deloitte partner looked over my resume and said that I would be a great fit for their data science department – who was I to say no?
I found working for Deloitte a fascinating study into how a professional services company operates, and was able to learn how I could excel in data science.
While Deloitte may be the golden goose for many people looking to get into the industry, don’t shoot only for the biggest names. I had such a great experience there, not because it is a well-known multinational firm, but because they allowed me to apply my knowledge and boost my skills. This is what anyone new to the industry needs to excel – the chance to develop. Just select an industry and explore the many types of companies within it.
That’s what I wanted from my next job: creating and building on the things I had learned. When I was recruited by a pension fund, they had me develop their data science division from scratch, devise a way to help its organization to work together on their data and deliver a different approach to customer experience.
I had a great time working there, but that got me itching to work for himself. Once I felt I was ready and had gathered enough experience, I made the leap into entrepreneurship and started to create Udemy courses on data science.

How Can I Future-Proof My Job?
As data grows exponentially, it stands to reason that we will need more data scientists to produce the tools that can handle it. This might make us believe that a career in data science is safe from automation.
This, however, is not the whole story – the better we get at producing tools to cope with data, the more automated we make our own field. There are robots that can handle the entire data science process, without any need for human interaction.
So, will data scientists get replaced by their own algorithms?
Hadelin and I have discussed this exact matter with Jeremy Achin, CEO of DataRobot. Achin and his team have created a self-serve ML platform where anyone can upload their data for a machine to process. These robots are hardly rudimentary. They allow you to get insights not only from your inputted data but also for a specific problem in need of a solution. DataRobot is one of many companies automating data analysis.
We know the way that the field is moving, and we don’t want to sell you any false dreams that, if you become a data scientist, your job will be 100 percent secure. The way to keep ahead of the game is to understand that while a data robot may indeed push out the number crunchers, data science is also reliant on people dreaming up new ways to capture, store and process information.
A machine might be able to do things more quickly, and even to identify the optimal solution for a task, but it cannot (yet) devise entirely new approaches to a data science project.
Think about it — is it harder to follow the rules to get results, or to work out entirely new pathways to achieving them?
Getting into the field right now is the best time to upskill to a level where you aren’t doing the “at risk” tasks, protecting you against the threat of automation. The best advice we can give is therefore to focus on strengthening your creativity.
For more insights into future-proofing your career, there is only one real advice to follow: Keep yourself curious, keep yourself hungry and learn as much as you possibly can. Even though there is a data tidal wave moving this way, we don’t want to alarm you, with it comes hundreds of new and exciting opportunities. You only need to be prepared and the best way is to get started right away.
How Can I Future-Proof My Job?
When Should I Get Started in Data Science?
Considering the field is in its relative infancy, some people wonder whether it might be better to wait until it has grown before getting their feet wet. If you’ve read the previous point, you should know our answer to this question: there’s no time like the present.
Companies are starting now to introduce data science teams to their organization – even those whose core output has nothing to do with science! We live in a highly competitive world. Savvy companies understand that to stay in the game, they need a data science team to gain insights into customers and business operations that give them a competitive edge, ensuring they aren’t driven out of the market.
This means that when one company starts to use data science, its competitors will have no choice but to follow suit.
If we consider that the population of the US is close to 400 million, this would effectively mean that well over half a percent of the U.S. population will be in data science this year! Data science jobs typically remain open for 45 days, which is “five days longer than the market average” according to Burning Glass Technologies. This means that it’s 10 percent harder for companies to fill these roles, which tells us that the personnel are currently not there.
So, what are you waiting for? Get into the field now however you can, whether it’s in education or practice, and ensure you’re a part of the community of the future.
