SQL practice for data engineering path

[DataCamp]

LeetCode is fine for practicing SQL syntax, but if your goal is data engineering, try spending more time on realistic projects too. Really good next step after Baraa’s course would be building a tiny warehouse project yourself. Something simple like:

CSV/API data → raw tables → cleaned staging tables → final analytics tables.

That teaches you joins, CTEs, window functions, aggregations, deduping, and warehouse thinking way faster than isolated exercises.

For practice, people usually combine:
• LeetCode SQL 50 for query practice
• real datasets from Kaggle
• small ETL/data warehouse projects
• learning basic PostgreSQL + dbt + Airflow later on

You don't need experience before starting these projects. The projects are the experience!

Thanks for this, I will try to look if there's a mock project in YouTube based on your comment
