If you’ve been preparing for a data engineering job at companies like Meta, Amazon, Apple, Netflix, or Google– often called MAANG- you might have noticed something surprising. They don’t just ask questions about tools like SQL, Python, or cloud platforms. They also ask about data structures and algorithms!
This might seem confusing at first. After all, as a data engineer, your job is to work with data pipelines, ETL processes, and databases, right? So, why do you need to know data structures and algorithms (DSA)?
In this blog, we’ll break down why MAANG companies ask these questions and why they are important for data engineers.
