>Also, there was the overall arrogant tone: "I found their interview approach a bit of a turn off so I did not proceed to the next interview and ignored her emails ", this just shows a lot of immaturity.
I'm not saying you're one of these people, but it's frustrating when companies do this to potential employees and the potential is told by friends and other management type people, "well that's the company you just have to deal with it".
When someone flips it on the company then it's immature.
I applied somewhere recently and they invited me out to a pre-interview lunch. That went well so they called me in for an interview. That went well and the VP told me he would call me back to set up a second (third?) interview.
I never heard back from him. An ex-coworker there went to the VP to find out what was going on and the VP said he decided he wanted someone with more experience in the specific area they're working in.
But last he told me was he liked me and would schedule another interview, then when he changed his mind he never let me know.
I think people on both sides should be courteous and respectful through the process, but if employers are treating interviewees poorly then they shouldn't be surprised when they start getting treated poorly.
