Microsoft 𝗣𝘆𝗦𝗽𝗮𝗿𝗸 interview questions for Data Engineer 2024.

1. How would you optimize a PySpark DataFrame operation that involves multiple transformations and is running too slowly on a large dataset?

2. Given a large dataset that doesn’t fit in memory, how would you convert a Pandas DataFrame to a PySpark DataFrame for scalable processing?

3. You have a large dataset with a highly skewed distribution. How would you handle data skewness in PySpark to ensure that your jobs do not fail or take too long to execute?

4. How do you optimize data partitioning in PySpark? When and how would you use repartition() and coalesce()?

5. Write a PySpark code snippet to calculate the moving average of a column for each partition of data, using window functions.

6. How would you handle null values in a PySpark DataFrame when different columns require different strategies (e.g., dropping, replacing, or imputing)?

7. When would you use a broadcast join in PySpark? Provide an example where broadcasting improves performance and explain the limitations.

8. When should you use UDFs instead of built-in PySpark functions, and how do you ensure UDFs are optimized for performance?
