What's the criteria for adding a tool? Each tool here shows up frequently on data engineering and data analyst job descriptions at mid-to-large enterprises. The track structure is consistent: start with installation and the workspace tour, then build something real, then cover the interview questions. The goal isn't to teach every feature — it's to make you ready for the interview and your first week on the job.
