Applied online then contacted by email for phone interview. During call interviewer was very arrogant with poor english but good technical skills. I confused because of his speaking and mess up with very basic techical questions. At the end he asked if I have questions and after I asked he refused to answer (my questions was not related to confidential information). Advice to hiring managers - please choose nice people as an interviewer, this is first impression about your company. I am not going to personally apply for any more positions or to suggest somebody else.
