You've already got a bunch of replies, still like to add something. I'm in the "I never felt anything towards coding" category. Tried to grow passion for it, just doesn't work. But I'd still be thrilled (and possibly intimidated) to see a passionate developer showing up for an interview. That these interviewers didn't get that you have passion for the work itself and not its outcome, not a great sign.

Hope you found something more fitting for your personality.
