User found existing online course platforms unstructured for advanced topics like SQL window functions and CTEs, indicating a need for more guidance and structured content for complex subjects.
I recently failed a technical SQL live coding exercise for a Sr. Data Engineering position and realized my SQL skills are in the gutter right now (thanks, Claude). If you had a couple of months to study, what platform or course would you recommend? I've tried Datalemur previously, but it's a bit unstructured for me, and I feel like I could have used more guidance for the advanced topics like window functions and CTEs etc. It seems like there are a lot of sample problems online, but not a lot of actual instructional content - but maybe I'm not looking in the right places? I am willing to pay for a course/certification if it's good enough.
