What Does a Data Scientist Actually Do?
A data scientist is responsible for finding meaningful patterns and insights in large volumes of data. They turn raw data into actionable strategies, reports, and predictions using programming, mathematics, and domain understanding.
In simpler words, data scientists help companies make smarter decisions, from recommending the next product you should buy to predicting stock trends or preventing fraud in banking.
They work with: - Structured and unstructured data - Predictive models and statistical techniques - Tools like Python, SQL, Power BI, and machine learning frameworks

How to Become a Data Scientist in 3 Months
It's absolutely possible to become job-ready as a data scientist within just three months, provided you follow a structured, project-based learning path.
In the first month, you should build your foundation by learning Python, Excel, and core database logic with SQL. This sets the stage for working with structured datasets, writing queries, and performing basic data manipulations.
During the second month, your focus should shift toward tools and analysis: - Learn how to clean, visualise, and explore datasets using libraries like Pandas and Matplotlib. - Build dashboards using tools like Power BI. - Start learning machine learning concepts using Scikit-learn and apply them to real datasets.
In month three, it’s all about preparing for the job market. Alongside completing hands-on capstone projects that simulate real business problems: - Optimize your resume and LinkedIn profile for data roles. - Begin mock interviews and apply to internships or entry-level jobs across analytics and data science teams.
This approach is not theoretical, it’s the same path followed by our learners who landed data science roles through CDPL’s job-ready curriculum.
