Adecco interview questions

One of the standout questions they asked in a data engineer interview was to design a data pipeline architecture for a real-world scenario. For example, they might give a use case like streaming customer transaction data from multiple sources, requiring you to explain how you would ingest, transform, and store it using tools such as Snowflake for warehousing, Airflow for orchestration, and Python for ETL scripts. The goal was to evaluate not just technical knowledge but also your ability to balance scalability, fault tolerance, and cost efficiency in your design.Another common type of question is explaining how you would optimize queries in Snowflake or handle schema evolution in a growing dataset. They often want to see if you can connect theory with practical implementation.
