Deloitte Contractor interview questions

It was very simple, the Contracting company scheduled a call with a technical person from deloitte, which was followed by another simple technical discussion with the Manager, followed by Hr interview from Deloitte. the interviewer was an experienced person.

Phone interview. The interviewer repeatedly interrupted while I was answering the questions and wouldn't let me finish or give complete answers. She then proceeded to tell the answers to questions I wasn't allowed to finish answering and asked 'did you know that'? At one point I considered just hanging up as she was basically interviewing herself. The whole interview was rushed, the interviewer was impatient, rude and condescending. Disgraceful attitude from what I previously considered a respectable company.
