Then ask about browser caching, expires headers, js/css minimization, yslow (or page speed :/), CDNs, and generic front end stuff

A non-trivial percentage of visitors hit Google Search with an empty cache and no cookies. I know the numbers but aren't sure I can share them, but it's enough that relying on caching to solve latency woes doesn't work.


In 2007 Yahoo shows that ~40-60% of users hit their pages with an empty cache[1].

Newer numbers would be good :)

That's fine, but are you asking your frontend devs to solve Google's latency woes as a normal part of their interview?


From my experience, they do ask those questions.
