I'm looking for something similar for design interview practice purposes in my job hunt.

All the systems design resources I can find are aimed at L4/L5, where the focus is e.g. on how to implement a rate limiter on a single machine, or at best saying you can distribute it by putting the counters on a cache server.

I'm trying for L6 and can identify many of the issues with a L5 design (redundancy, sharding, global latency, hot spots, local batching), but it's hard not to miss the obvious, and to offer practical/realworld solutions, when my day job is embedded compilers and not large scale systems.

This is mostly a rant but I appreciate suggestions.
