Technical Phone Screen - System Design
What to Expect
First technical phone screen focused on system design and architectural thinking. You'll be asked to design a large-scale system relevant to DoorDash's domain (e.g., real-time delivery tracking, order routing, data pipeline for analytics, or similar distributed system). The interviewer evaluates your ability to think about scalability, data architecture, trade-offs, and technical decision-making. This is a whiteboarding-style discussion over video call where you explain your approach, make design choices, and justify trade-offs.
Tips & Advice
Structure your approach: clarify requirements, estimate scale, define APIs, design data flow, then discuss trade-offs and optimization. For DoorDash domain problems, focus on real-time data, low-latency requirements, and operational complexity. Draw diagrams, discuss database choices (SQL vs. NoSQL, data warehousing), caching strategies, and message queues. Be prepared to dive deep on specific components and explain why you chose certain technologies. Discuss monitoring, reliability, and operational considerations. Show familiarity with technologies mentioned in job postings (Spark, Snowflake, Databricks, Kafka, AWS).
