NBCUniversal interview questions

First couple of rounds were okay. It wasn't until the final interview when they started to really show their unprofessional and inconsiderate behavior. Two days before the interview, I get an email from the recruiter that it's been cancelled without any reasoning and she reschedules the date without asking if it works for me. Then on the day of it, I get a text from the hiring manager an hour before the interview (like seriously?) and she tells me that the panel interview has been cancelled and there will just be a phone interview instead. So I had to drive there for nothing. They really seem unfazed and oblivious about their actions. And not surprisingly, they didn't bother to let me know if I was moving forward in the application process either. After this whole mess I wondered why I ever applied here in the first place.
