I was interviewed for a brand new startup, which is now worth +$20m, and I really liked the idea and founder behind. When I met with her, I was blindsided by another developer, who was gonna ask the questions (which is fair!) - I simply weren't informed.

The meeting went on, and seemed great, however we started talking about bug tracking, and I mentioned that I liked "New Relic" (no more!!) and he, the developer, obviously did not, as the mood suddenly changed and he started bitching about it being expensive, and that there were better alternatives.. The meeting endes shortly after, and I was told by the founder that she'll contact me.. Never happened. However I was told by the developer who was hired instead of me, that "another application was rejected due to personal preferences"..

May be small problems to anyone but me, but I just find it disgusting, and it's typical developers to be so high and mighty about their choises ("X language sucks, you should use Y")

I don't blame the founder at all, and I've supported their company since (minus ranting about the shitty product that they ended with)
