This was probably the most negative experience I had ever encountered for a phone interview. The interviewer was condescending and rude in his remarks, such as "The things on your resume are just claims" (before he even got to assess my technical abilities), and "Since you were not able to correctly answer this question, I guess you won't be able to answer the next question I am about to ask you." I was distraught at the level of unprofessionalism and undermining I received during this interview, because never have I ever in the history of interviews had I ever encountered this. With the way the interview went, I was 100% sure I wouldn't receive an offer, but at the same time, I wouldn't want to work in a company where leadership talks down to you in a condescending manner.
