Do you see any evidence that candidates are blindly copying stuff around?

Also, you fail to offer any explanation on why studying systems design topics is supposedly inferior to not studying and just expecting to wing it at job interviews. You only assert that hypothetical candidates indeed have a broader technical background than you, but their knowledge and expertise are useless when compared to your uneducated improvisation skills.

Explain why you expect it to make sense?

> I think the answer lies somewhere in the middle. I don't disagree that you should be aware of these things, but drawing out the same system diagram as Netflix without actually having measured a real system to understand where the hotspots are is ultimately just guessing, at best following a known pattern without evidence it's required.

Why do you believe this hypothetical scenario is a concern? I mean, either this approach is useless and candidates have no advantage in following it, or this approach is enough to get candidates to outperform you at job interviews. In both scenarios, why do you think that others regurgitating information is a problem?
