1,000 grader interview questions shared by candidates

The interview mainly focused on: Python fundamentals Object-Oriented Programming (OOPs) concepts Data structures and algorithms PySpark internals (how it works behind the scenes) Data pipeline design based on scenario's for batch and streaming processing Writing code in SQL, PySpark, and Python One of the coding questions was about grouping anagrams in Python. During the interview, it was emphasized that when solving problems, you shouldn’t just write code directly. Instead, you should explain your thought process - Why you are choosing a particular approach What the next step is and why it makes sense How your solution handles edge cases or scales So the expectation was not only to provide the solution but also to walk through the reasoning step-by-step.
