10 Pyspark questions to clear your interviews.

1. How do you deploy PySpark applications in a production environment?
2. What are some best practices for monitoring and logging PySpark jobs?
3. How do you manage resources and scheduling in a PySpark application?
4. Write a PySpark job to perform a specific data processing task (e.g., filtering data, aggregating results).
5. You have a dataset containing user activity logs with missing values and inconsistent data types. Describe how you would clean and standardize this dataset using PySpark.
6. Given a dataset with nested JSON structures, how would you flatten it into a tabular format using PySpark?
8. Your PySpark job is running slower than expected due to data skew. Explain how you would identify and address this issue.
9. You need to join two large datasets, but the join operation is causing out-of-memory errors. What strategies would you use to optimize this join?
10. Describe how you would set up a real-time data pipeline using PySpark and Kafka to process streaming data

Remember: Don’t just mug up these questions, practice them on your own to build problem-solving skills and clear interviews easily
