I work for PA and really enjoy the people and the work. I am not sure which office you interviewed at several years ago, but the offices are very smart now. I agree that the quality of the interviewer has a big bearing on ones impression of the company and am surprised to hear that you had a poor quality interviewer at PA. In my experience at PA, I would say the type of person you have described is very much in the minority, and cannot think of anyone immedidately who would fit into this category. The average quality of a person in PA is very high relative to other consultancies I worked at, both in terms of how personable they are and also how talented they are as a consultant.
