CaptiveAire interview questions

I spoke with two HR representatives on the phone separately at length before getting an in-person interview. I found another open position at the company that better suit my skill set prior to the interview. I asked her if I could be considered for that position too and she said the pay was the same but it required more work and dropped it. I got the impression she either wasn't responsible for filling the other position or wanted to fill the one I originally applied for more. The in-person interviews were interesting. I waited almost ten minutes after I got there on time for my interview for the first person to see me. People are busy, I understand. I'm unclear why someone from HR didn't greet me when I arrived though. I met with three people, the first I felt I had a good rapport with and learned a lot about the day-to-day tasks. The second person was nice enough but I was taken to his office which had children's toys strewn across the floor. Didn't get the impression he was truly engaged with interviewing me, felt more like he was asked by the others to kill time until the third person was available. Third person was okay. One thing that put me off was I learned it's best not to ask questions, especially to the higher ups. I was told if I needed to contact an application engineer for information, I had to have my boss send the email because they're super busy and easily annoyed.
