Welcome to the Databricks ecosystem, @shinybrightstar!
I would suggest you visiting the Databricks Academy which provides you with amazing free, self-paced courses. You could begin your journey with completing the Databricks Fundamentals badge which helps you learn about the platform basics. Next, dive into the Get Started with Databricks for Data Engineering which provides a basic understanding of data engineering principles and topics such as data collection, extraction, ingestion, and transformation.
Get your hands dirty on the Databricks Free edition to build, automate, and govern data pipelines. Your ultimate milestone should be passing the Databricks Certified Data Engineer Associate exam. The exam guide also provides a list of self-paced (available in Databricks Academy) training which helps incredibly to learn the Data Engineering concepts.
Happy Learning to you and All the very best !!
