When somebody asks you about passion, they're asking you if you're willing to work unpaid overtime. Case closed.
Imagine if someone responded "My children are my passion" or "teaching Sunday school" then - whoops! now the conversation is in a very tricky area where it's all to easy to ask questions which may be regarded as evidence of intent to discriminate.
Instead, I interpret it that the interviewer is using popular buzz-phrases. And if the interviewee doesn't know the buzz-phrase then it becomes an indication of a so-called "bad cultural fit."
Which is all too often another way to say "too diverse for us".
