I interviewed with a manager and then two partners. The interviews were relatively casual and friendly. The interviewers were dressed well and prepared with questions and had my resume printed out. We met in the conference room. They asked questions specific to auditing and project management (i.e. Tell me about your more rewarding professional experience thus far, what is your favorite phase of the audit and why, etc) and also my personal life (i.e. how do you spend your free time, how would you describe yourself,etc). They will call all of your references!
