Your question is Data Architecture Challenges. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Discuss a data architecture you have worked on and the challenges faced.
Focus on one architecture you owned end to end, including source systems, ingestion, transformation, storage, orchestration, and data quality controls. Explain the scale, the bottlenecks you encountered, and how you handled failures, schema changes, or latency issues.
