In my opinion to get started you need to have a good SQL skill, some python knowledge and some basic understanding of data modeling. I met in my life data engineers who were good at technical skills but they didn't have fundamental knowledge about data modeling.

If you learn that fundamental blocks like SQL and data modeling then you will find a lot easier to pickup different technologies. It won't matter if it will be Databricks or Snowflake or Redshift. Because in the end - those are just tools and if you know what to do you can easily learn tool along the way in a job 🙂
