I've mentioned it on the blogpost but: Do you have some metrics about the success of your candidates replying to those questions?

These are not actually interview questions.

Well, I know that there are "interview questions", but they are trying to show us the kind of knowledge that is needed to join a Company as Cloudfare so I am pretty sure that some of those are going to be questions in some point of their interview process.

I just wanted to know that in case that the questions are formulated that way, what's the ratio of people that can successfully answer those.

mu out of zero people asked successfully answered.

The article says:

"For quite some time we've been grilling our candidates about dirty corners of TCP/IP stack. Every engineer here must prove his/her comprehensive understanding of the full network stack. For example: what are the differences in checksumming algorithms between IPv4 and IPv6 stacks? I'm joking of course, but in the spirit of the old TCP/IP pub game I want to share some of the amusing TCP/IP quirks I've bumped into over the last few months while working on CloudFlare's automatic attack mitigation systems."

That is, these are not real interview questions. They are trivia questions.

I doubt most engineers even at Cloudflare can answer these without research.
