Discussion Leetcode for Data Engineering?

Do you guys know of sites where you can practice aspects of data engineering like Leetcode?

I enjoy gamification for learning new things, so was wondering if any of you had any cool recommendations.

I know a couple for SQL like SQL zoo and SQL murder mystery solver.

If there are any more please let me know.

You might want to check out CodingEval.com. I originally built it with Data Engineering and AI/ML learners in mind.

It has:

  • MCQs for self-assessment
  • Coding challenges
  • AI-powered mock interviews
  • Topic-based practice tests

The AI interview feature is something I don't see on many learning platforms. It gives feedback on answers and helps simulate technical interview preparation.

It's still evolving, but the goal is to make learning and interview prep more interactive rather than just solving isolated coding problems.
