I had a phone interview for a teller job. They ran my credit prior to the interview and told me my credit is fine for now but in the future I may need to provide documents to prove that I’m paying on a collections account.

So I had a phone interview for a teller job paying $17/hr. They already ran my credit and brought up a collections account during the interview. I explained the situation and the hiring manager told me it’s not an issue as of now but it can become one in the future and they may require me to provide documents to prove I am paying on the collections account. This seems odd to me? I understand that the banking industry runs credit credits, but if my credit is okay right now, why do I need to provide proof later that I’m paying on it while already employed? Does this seem weird to anyone else or is it normal in the banking industry to provide this documentation? I feel that’s personal and if they already ran my credit and said it’s fine, why can it become a problem in the future?
