Received phone calls to make sure time and address before on site interview. On the day of interview, same process as other major companies, On the day of interview, same process as other major companies

I submitted application and got on-site interview directly, then they arranged my interview on one afternoon, but they don't cover the travel expense, so I booked the flight by myself. One day before the interview, they emailed me and informed me the position is taken, so my interview is canceled, although I already arrived at San Jose at that time for interview. They don't care my cost on flight ticket at all so that I lost $500, two days and an interview opportunity. I don't what to say about it, if you decide to choose one candidate among applicants, you should at least interview all the applicants that got interview opportunity. It concerns with the reputation of the company!
