When your interviewer (VP, etc) shows up in a T-Shirt.

I'm all about not showing up in a suit and tie and wearing things you never wear just for an interview, but at the same time, showing up prepared and appearing somewhat professional indicates your level of care and interest towards something as well.

Top all of the above off with a person firing off the basic of ridiculous questions at you.... tell me about a time you failed at something, what adjectives would you use to describe yourself, asking questions; firing them off like a gun magazine....oh wait, we have barely any minutes left, what questions do you have.

Like WTF?

Update to this:

The point behind this post is that when people aren't showing up prepared or engaged to the interview, it's a solid sign they aren't giving you serious consideration. You may have seen the same in your sales deals.

Point in fact, I am not moving forward in the next stage, but I had no desire to do so after this occurrence anyways.

Generally, people tell you what's going on without telling you what's going on. Don't waste your time being upset by it, just move on, identify what those flags are, and prevent them the next time they occur.
