You’ve got “Data Engineer” on your résumé…
But can you actually answer these questions?
In this video, I’m going to test whether you truly understand what real data engineers do—or if you’ve just been stacking buzzwords on LinkedIn.
These are the three questions that instantly separate résumé engineers from system builders:
✅ When would you use a window function instead of a GROUP BY?
✅ How do you handle late-arriving data in an incremental pipeline?
✅ How would you model historical price changes in your tables?
If those questions made you pause, that’s your roadmap.
I’ll break down what real data engineers know, why titles don’t make you one, and how to actually earn the role through SQL, data modeling, orchestration, and governance.
Whether you’re coming from analytics, software, or just starting out—this is the truth about what separates data professionals from true engineers.
