CyArk interview questions

This company really needs to understand professionalism regarding their interview process. I showed up for a first in person interview. They were unprepared for the interview and I waited for a bit in their "lobby". The first inkling of weirdness came when I was sent an email for a follow-up interview with the VP. They schedule me for a meeting for the morning of the following Friday. I schedule the time off with my present employer to account for this meeting. I get another email later that day, re-scheduling the meeting to 2 PM. I then have to submit another schedule request form to 2 PM off for that day. A day passes: I get another email apologizing that the meeting will have to be moved to the following Wednesday. I have to push back a little here because my current jobs needed me for that Wednesday and I have already reserved/cancelled a few times off for CyArk. They agreed to Friday of that week, sending me yet another email confirming my meeting with the VP. I tentatively reserve a space in my calendar for that day off. Four days pass and I get an email from Brinker (the head of hiring at CyArk) saying they have decided to go with another candidate and basically giving an email basically saying how despite this I should feel lucky to have been offered the chance to have made it this far in a pool of applicants. Right there, showcases the problem here. As a company, you are lucky to have professionals consider and work for you. We as applicants are not the lucky ones. Also, you as an organization are lucky that people like myself will take times out of their schedules to interview for you. If you schedule an interview, it is extremely unprofessional to constantly change the date and time, as well as even back out completely. Here though, is where we witness an even greater problem: an organization that has no respect for a person's personal schedule and time is a red flag. It shows what they think of you as an individual. Considering this is a non-profit organization, I expected more of an awareness to the human element involved here.
