This hard-level SQL question appears frequently in data engineering interviews at companies like Adidas. While less common, it tests deeper understanding that distinguishes strong candidates.
This is a senior-level question that tests architectural thinking. Lead with the high-level design, then drill into specifics. Discuss trade-offs explicitly - there is rarely one correct answer. Show awareness of scale, fault tolerance, and operational complexity.
Situation: Business wanted real-time dashboards; infrastructure was batch-only. Task: Deliver value within constraints. Action: Proposed hybrid: (1) Batch for historical (nightly). (2) Near-real-time (15-min) for recent data via incremental streaming. Delivered MVP with batch first; phased streaming in Q2. Communicated trade-offs; aligned on phased approach. Result: Met 80% of requirements with existing stack; streaming added later. Leadership: Framed options; didn't over-engineer for theoretical needs. Outcome: Balance of business goals and technical feasibility.
