Airspace Systems Senior Robotics Engineer interview questions

So it takes a week or two to set this up. I go over. I do all the talking. No discussion of job responsibilities. It's kind of a show and tell on a proto. They walk me out the door and said we'll be talking, I'm scratching my head. Days go by and I hear nothing. We go into this cat and mouse game for weeks on salary negotiation. They come back to me after having to pester them about updates and then tell me that they don't have funds to hire this position now.
