How does system design for industrial recommendations and search look like? In this talk, Eugene Yan shares how its often split into:
- Latency-constrained online vs. less-demanding offline environments, and
- Fast but coarse candidate retrieval vs. slower but more precise ranking

We will also see examples of system design from companies such as Alibaba, Facebook, JD, DoorDash, LinkedIn, and maybe do a quick walk through on how to implement a candidate retrieval MVP.
