      Top 5 Technical Interview Questions Asked Data Engineer

      • Answer: ETL (Extract, Transform, Load) transforms data before loading it into the target system, which is ideal when working with limited storage or complex transformations. ELT (Extract, Load, Transform) loads raw data first and then transforms it within the target system, commonly used in big data contexts where storage is abundant and parallel processing (e.g., with Hadoop or Spark) is leveraged.

      Answer: Start by analyzing the query execution plan to identify bottlenecks. Use indexing to speed up data retrieval, avoid using SELECT *, break complex queries into simpler subqueries or temporary tables, and consider partitioning large tables. Also, ensure that statistics on the tables are up to date.

      Answer: I’ve worked with Hadoop for batch processing large datasets and Spark for both batch and real-time processing. I implemented data pipelines using Spark’s RDDs and DataFrames, optimizing performance by tuning memory usage and leveraging Spark’s in-built transformations and actions.

      Answer: I implement validation checks at each stage of the data pipeline, including schema validation, range checks, and null handling. I also use automated testing, monitor pipelines for anomalies, and employ versioning for data and schemas to track changes.

      Answer: Partitioning divides a large table into smaller, more manageable pieces, improving query performance by allowing the database to scan only the relevant partitions. This also aids in maintenance tasks, such as archiving or purging old data, and improves storage management by distributing data across multiple disks.
