Ah. My mistake, I'd guess that is likely to get staff+ level interviews at Big Tech.
>Interesting, I've heard that opposite. Good feedback.
That managers have to do DS&A coding rounds at FAANG+? Maybe some, I don't think the bar will be near as high as the IC route.
>Good idea. What do you think the best way to go about that is?
Well, I don't think this is something you can fake, but if you've been working on deep tech, you don't have to fake it.
I'd go against the grain of reading 'system design books' and say instead read (some of) the actual code and design docs for large popular web scale open source projects (stuff like K8s, PostgreSQL, Cassandra, memcache, Spark etc).
That should be enough to get a deeper understanding of how to design large scale systems.
Then do a few practice interviews at some place like pramp.com or interviewing.io, just to get used to talking about it with someone.
