The interview was conducted by an engineering supervisor and someone from HR. The woman from HR was very kind, and asked all the right questions. The engineer was very abrupt. On many occasions, the engineer interrupted the HR rep's question to me. On at least three other occasions, he interrupted my answer. I found him to be rude and unprofessional. It made the interview difficult, and because of how the engineer I decided to turn down the eventual offer made to me. I did not want to work for someone who conducted himself like that.
