solution to questions of lab equipments and funding search during faculty interview
Fortunately, as a post-doc you should have access to two people to discuss this with. The first would be your PhD advisor, and the second your post-doc advisor. In most cases (yes, this SE gets many bad stories, but there are many more good endings), these people will want to help you continue in your career. 

You PhD advisor is a professor, so went through this exact kind of interview at some point, and has likely seen it from the hiring side as well. If your post-doc is at a university, well, you get a second view of that process. If your post-doc is in industry or a national lab, it is highly likely that they either applied for tenure track positions at some point, have friends who did so, or have had other post-docs do so. Further, to get their positions they went through a slightly different interview process, but that still sheds light on how to approach an interview in general. 

I have always been interested in helping anyone who worked for me to fulfill their goals. Perhaps they don't work for me anymore, but they are 'my' people forever.
