Teller's interview questions

They have sent me an email for online interview. After that video interview, since I was very nervous about that I went to that advertised branch, and its manager gave me an interview for the next day. I was interviewed by the assistant manager and manager. They liked me a lot and told me that I was very good and had whatever they wanted. But the manager told me there was one more candidate to interview, so we would call me in two days. Then I left, but forgot to ask for business cards , so I came back but manager was gone, and his assistant gave me their cards. The day after, around 11 AM they sent me an email and said that they have chosen somebody else. I was pretty upset because they were very interested about my resume and my personality.
