How to Actually Prepare for System Design Interviews (with Airbnb Software Engineer)

In this mock system design interview, I'm interviewed by a software engineer from Airbnb. We go through a simple system design question involving finding locations on something similar to Uber. In the end, we end up getting feedback on how to perform well on system design interviews as well as what parts of our system design went well. Feedback: The good parts: Built a grid system design to group together rovers in the same area. Separated tile data from driver data to allow for separate indexing. Discussed and addressed various storage concerns, came up with good solutions. Mentioned cleaning up / normalizing the GPS data. The not so good parts: Could not provide the hashing function from coordinates to the tile id. Initial design using a center point and a radius - not flexible, difficult to build on top of. Note: Similar system design questions include Yelp, airplane tracker, food delivery, etc. Other viable solutions for spatial indexing are Quad-trees and R-trees. Score 4/5 Self-review: 3/5
