The Perth Mint interview questions

I submitted my application online and the next day i received a call from HR. When i picked up the unknown mobile phone call she immediately asked me to hold. After 3 minutes of waiting she returned and just started talking about an application i had submitted without not even telling me her name or what company she was calling from. After asking her what organisation she was calling from and who am i speaking to, she apologized and then started telling me how she is having a "stupid dumb day" having to deal with silly people.
