Job Interview With Gigante Law Firm

I've actually always tried to avoid working for a large firm, and at the time I sent in my resume to the one I'll be interviewing with next week, I had no idea they had well over 100 attorneys and offices in San Fran, L.A., New York and Hong Kong. Yikes! Anyway, since this firm has expressed an interest in talking to me, I figure I may as well see if I can impress them enough to maybe offer me a job.
