Hey PH! 👋 I built DataEngPrep because I was tired of scattered interview prep resources. When I was preparing for data engineering interviews, I found: - LeetCode is great for algorithms but weak on DE-specific topics - Random blog posts give surface-level answers - No single resource covered SQL + Spark + System Design + Python at depth So, I curated 1,863 questions from real interviews at 97+ companies and wrote every answer at Senior Engineer depth — with trade-offs, architecture diagrams, and pro-tips. The site is free to browse. All 1,863 question pages are public with partial answer previews. Full answers are behind a paywall. I'd love your feedback on: 1. Does the partial answer reveal useful or frustrating? 2. What topics would you add? 3. Would you use AI mock interviews for DE roles? Thanks for checking it out!
