In this video, we introduce Spark and PySpark from a data engineering interview perspective, focusing on purpose, usage, and real-world relevance. You will learn what PySpark is used for in data engineering projects, why Spark is preferred over traditional processing tools, and how interviewers evaluate basic Spark and PySpark knowledge. This session is designed for absolute beginners, data analysts, and career switchers who want a clear mental model of PySpark before moving into transformations, pipelines, and production use cases with Databricks, AWS Glue, and Azure Data Factory.
