NuVision Federal Credit Union interview questions

I received a called from the assistant hr, and set up a date for face to face interview. On the day of the interview, I was set in a meeting room where I had five different people asking me questions. It lasted like an hour and the next day I received a phone call from the assistant hr. I was inform that they where going to do a background check before they make a job offer and after that I didn't heard back. The weeks pass and I didn't hear back, then I emailed and called assistant hr lady several times, but no answer back. I still assumed the background check hasn't concluded. After a month pass I didn't hear back and gave up. I never received a notice from them if I qualified or not. After month the assistant hr lady email me that the position was filled.
