> That should be enough to get a deeper understanding of how to design large scale systems. Both my startups actually hit scale so I already know system design pretty well. I was actually an early adopter for K8s and we were using Docker before it was even GA. What I don't know is how to interview for it, since a down side of working at a startup is you have very few sounding boards to catch up with terms of art. The priority is on shipping. I'll check out those sites you mentioned. Thanks!
