I had a call with an HR, and followed up with a technical interview. The interviewer in the technical call was pretty unprofessional. He didn't seem to understand the nuances of the language we were talking about, and he didn't grasp the questions he was asking. When I asked him to clarify his questions, things went south and the interview come to a place that I can't continue. I informed the HR about the situation and asked to be matched with someone who has proper Python and interview management experience, but got no response.
