I once was interviewing for an interesting job and the topic was general knowledge of a system made of A, B and C (all were similar). The interviewer did not know much but insisted on some very deep details about B. I told him more than was available in the docs already and at some point I said I would need to peek in the code to say more.
He told that this was too difficult for me because only people who were part of the team who designed that would understand.
I told him that I wrote almost by myself the A part so it won't be too difficult to catch up with B.
I did not get the job (ultimately a happy ending) and was told that I did not know enough on A (the part I wrote).
I am joking but not really, basically it's my belief that any place asking for 10 years of a 5 years old technology is going to be really sensitive about anyone with an "attitude"
interviewer in 1999: we are looking for someone with 10 years of java experience.
james: I invented java 5 years ago.
