Data Extraction Tips & Takeaways

1. Connect technical decisions to business outcomes: Justify why your design makes sense based on the business need—whether it’s real-time customer insights, cost-efficiency, or data accuracy.
2. Be ready to discuss trade-offs: FAANG interviews focus on conflicting requirements—balancing cost, complexity, scalability, and performance is key.
3. Plan for growth: Ensure your design can scale by 10x or 100x. Highlight how your pipeline design adapts to growth.
4. Communicate clearly: In addition to technical depth, clearly explain your decisions to both technical and non-technical stakeholders.

By focusing on these principles and addressing trade-offs, scalability, and real-world problem-solving, you will be well-prepared for the ETL pipeline design interviews at FAANG companies.
