Your mistake was talking to an HR person. They are bureaucrats who understand nothing about our craft and only look for obvious reasons to disqualify you. Your goal is to say as little as possible and get past HR quickly to talk to an actual technical person who can make the appropriate trade-offs. You could be the next Donald Knuth and HR would still reject you for 4-day week because to them you look like [any other shmug + extra burocracy].
