I also had my resume submitted by a Big4 tax director and haven't heard from the firm, only for the recruiter to tell me that it is on file should this director's group have needs.

I also heard from another Big 4 recruiter that even if a partner submits your resume and you don't have the goods (for example low GPA), they still will not give you an interview.

While it helps for someone in the firm to submit your resume, I think HR still has to decide whether to give you an interview and another reason they don't is because there are currently no open positions.
