I use a structured approach: (1) Engineering blogs from companies at scale—Netflix, Uber, Meta, Databricks—for real-world patterns. (2) Conferences—Data+AI Summit, AWS re:Invent—for vendor roadmaps and peer discussions. (3) Communities—Slack (e.g., dbt, Airflow), Reddit—for...
This hard-level Behavioral question appears frequently in data engineering interviews at companies like Presidio. While less common, it tests deeper understanding that distinguishes strong candidates. Mastering the underlying concepts (airflow, optimization) will help you answer variations of this question confidently.
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.
I use a structured approach: (1) Engineering blogs from companies at scale—Netflix, Uber, Meta, Databricks—for real-world patterns. (2) Conferences—Data+AI Summit, AWS re:Invent—for vendor roadmaps and peer discussions. (3) Communities—Slack (e.g., dbt, Airflow), Reddit—for day-to-day trade-offs. (4) Hands-on—I run POCs or side projects to evaluate tech (e.g., Iceberg, Rust for data). I also share learnings via internal tech talks and design docs. I'm currently deep-diving into [e.g., Data Mesh, Apache Iceberg, cost optimization]. Result: I bring informed opinions to vendor and architecture decisions; I've introduced 2 tools that improved our stack. Lesson: Passive consumption isn't enough; apply and share.
