Seyfarth Shaw Case Assistant interview questions

I tracked HR down to fill a position that was vacant for 6 months (or longer). Once the ball got rolling, things went well during my 1st round interview. In the request for a 2nd round interview, I was informed I'd be interviewing with two separate groups comprised of two attorneys and a partner. The partner in the first group saw me, she said I was "overqualified" and tried to talk me out of the position that they "desperately needed to fill." While I waited for the second group to arrive, I heard them laughing aloud in the adjacent conference room before they came to interview me...it was terrible. Needless to say, I'm glad I didn't get a job offer with such an unprofessional firm.
