I did a phone interview with this interviewer and she was sarcastic and very rude. Everything goes well in the beginning till I posted questions about the position. She replied this is a replacement and the previous person is a super person. Can manage a few regions. Than, she asked do I know which countries are middle east. when I told her not sure, straight way, she replied sarcastic way that a supply chain planner must know very well of the geography. I was shocked! I have not come across such interviewer straight away point judgement. I would consider how is this company working culture be. It is very scary. I will not work in this kind of company.
