Luxury Mortgage interview questions

I worked with an (independent) Agency Recruiter and was invited to an onsite meeting at their office in Stamford, CT. I spent several hours there speaking with various employees. No offer of a break, glass of water, anything. My final interview was with (I believe) the CEO and he was incredibly rude. Overall, I regretted the time I wasted during the interview process and, had I met the Company Leader first, I would've immediately left.
