Build It Solutions Python/C++ Engineer interview questions

They asked a list of questions in what fields I have experience. Then I asked where they are from. Then the HR told me to look at the job description Then I asked her Argentina? Her reply was "I guess you have bad manner thank you for your answer but we are not a good fit for each other" Which really suprised me as I did not do anything wrong and she was the first person ever told me this in a job interview. She did not respond to my further enquiry when I asked why she found that offending.. That was very weird....
