Have you ever tried to implement the KMP (https://en.wikipedia.org/wiki/Knuth%E2%80%93Morris%E2%80%93P...) pattern matching algorithm yourself?

I tried doing it -- even with the knowledge of how it works, it took me at least a day to get to an acceptable implementation.

OK, so you are just going to assume that any interview you can't pass is broken?

There have been interviews I have failed and instead of blaming the interviewers I took the time to actually study the problem I was given. This has helped me become a better programmer.

No, i was just presenting a counter argument. I never had to actually implement KMP outside of uni though.

Interviews that require extra knowledge outside of what the job actually asks for are definitely broken.
