When I was hired it was thru WaMu's hiring processes so I am not sure how that has changed but at the time you applied online upon which if you met their qualifications the HR dept called you and did a quick interview/review of your resume. At which point they would then forward your resume to the banks that were looking for a candidate, the branch manager would call you and arrange the appt and you would interview with the manager and asst manager.

Easy enough interview process. Very straightforward. Just answer accordingly. Just looking for competent personnel. Asked about relevant experience and work ethic centric questions. Only two rounds. First on phone, second in person.
