Parexel Line Manager interview questions

The Screening interview was quite unpleasant and the HR representative was irritable, abrupt, unfriendly and it was obvious she did not enjoy her job. I have over 20 years of experience in the industry and some of the questions for the position were completely unrelated to the role. When I asked for clarification she was very obviously annoyed. I came very close to ending the interview about 15 minutes into it, but thought I would just stick it out. Not a place I would want to work if this is the climate! Very cold and impersonal experience.
