Phone interview is a typical textbook interview that you will find on HR website / books. They ask you questions and don't even listen to answers. The HR person on a phone seems disinterested in you. I have finished answering full question about difficult campaign saying " and it was a great success at the end we got 3 new clients on board"...and HR goes " thats great, thank you, so what was the outcome of this campaign was it successful?"...l almost laughed. l don't know if l will get to the face to face interview after that.
