Surgeon's Advisor interview questions

Applied online, had phone interview, ended up making it to 1/4 candidates. Traveled to Miami for final interview (at this point it was between 2 candidates) and the hiring manager WAS NOT THERE, then contacted me the next day (I had a 8 hour drive home) to see if I was still around to meet, which obviously I wasn't. I was supposed to have a final answer on a specific date, contacted the hiring manager and "they hadn't made a decision yet" .. this continued for over 1 week of no answer and eventually they stopped answering my emails. Unprofessional.
