**Disclosure:** I’m the creator of LakeBench, so this is a self-promotion post. I’m a Data Engineer, and I recently built **LakeBench** .. a learning and practice platform focused on Data Engineering. The idea was to bring the common things people need to learn and practice into one browser-based platform instead of having everything scattered across different resources. It currently includes: 180+ lessons SQL, Python, PySpark & Pandas 245 practice problems 45-Day Study Plan Mock Interviews AI Mentor Hints Browser-based practice without setting up a cluster The goal is to keep the learning experience practical and focused on actually writing code and working through Data Engineering concepts.
