Data scientist’s job description – What do they really do?

Here are some things data scientists don’t do. 

They don’t use test tubes. 

They don’t create chemical reactions. 

They are not hackers. 

It will not take decades to conduct research. 

Now that we have cleared that up, let’s delve into what data science is truly all about. This unique profession has taken the corporate world by storm. It is defined as one of the hottest careers of the 21st century. Some experts even call it — ‘the new oil’. With over 2.5 quintillion bytes of data generated daily, data scientists are in a powerful position to manipulate and monetise this meaningful information. 

Data is a massive and complicated collection of facts and figures that need methodical systems for better comprehension. Data scientists understand this. They work closely with data engineers and analysts to create unique solutions for complex, real-world problems. These professionals have a very specific set of skills and training. 

Data scientists create structures that help decode data. They lay pipelines and build a foundation to ensure all data is accurately processed. They also investigate and analyse data.
