How do I prepare for a data engineer interview as a fresher?
I know SQL and basic Python. What projects should I build and which topics come up most for freshers?

Build one end-to-end project: ingest a public API daily, store it in a warehouse, transform it with SQL and make a small dashboard. Interviewers love talking through a real pipeline.

Practise window functions and joins until they feel easy – almost every SQL round has them.

Also learn the basics of one cloud (storage, IAM, a managed database). It helps a lot in system design questions.
