Customer Support Specialist Interview Questions

The guy I was introduced to on arrival wasn't certain who was going to interview me, himself of the hiring manager scheduled to do so. I orientated myself whilst he texted his colleague. This guy was in jeans and a sweatshirt so I felt out of place in business attire. He started the interview and he informed me the hiring manager was not going to join us. He proceeded to tell me he had sixteen questions to ask me and began reading off the interview questions from his iPad screen. As I answered each question he took notes on his iPad making very little eye contact with me. It was very distracting. After all the preliminary formal screening it was not at all what I expected. The guy interviewing me clearly knew nothing about me and had a very vague idea about the specific position I was interviewing for and referred it as 'tech' position before I asked for clarification. The in-person interview really left me perplexed. I wasn't as well prepared as I could have been and the whole situation made me feel really uncomfortable. The company clearly has expanded quickly and their HQ in California is their main base and the other offices have just been tagged on to the same website/ vision/ values and outlook but the vibe was very different. I mistakenly walked into the downstairs office upon arrival & saw the tight cubicle space I would be working in. The website states their is no hierarchy but that is clearly not the case in this location.
