Spark and PySpark Interview Preparation Cheat Sheet

1. Creating data frames

2. Schema addition (data types)

3. Loading activities (CSV, JSON)

4. Column functions: select, selectExpr, filter, where, withColumn, withColumnRenamed, collect

5. Handling distinct values, drop, duplicate, orderBy, groupBy, fillna

6. Sorting and limiting

7. String functions: concat, split, trim, date, aggregate, null handling

8. Joins

9. Window functions

10. Cast functions, union, union all

11. Repartition and coalesce

12. PySpark broadcast variables

13. RDD vs DataFrame

14. Spark architecture: joins, partitioning, bucketing, optimization, and more

This Python interview kit is amazing! It has saved me so much time and made my practice sessions more efficient. I used to get lost figuring out which questions to focus on, but this kit provides a clear path—starting with various topics separately and gradually moving to intermediate-level questions. It has truly helped me practice quickly and effectively!
