Not true. I can think of a bevy of reasons that I'd be excited for a role that have nothing to do with being a cheerleader. For example, working in the banking industry for many years, I was tied down with a very rigid, sometimes antiquated tech stack. I started applying to smaller companies because I was excited about the prospect of having more autonomy and being exposed to a more modern tech stack.

I'd love to hear this answer. So much better to work with honest people, who's not afraid to call out BS.

yep! you nailed it. "because I have bills to pay" is the true reason. But they want some flowery "your mission really resonates with me" BS answer.
