PwC Executive Assistant interview questions

I was interviewed by 3 different supervisors who asked me about my different roles. They also were from different parts of the organization, so they talked to me about the different roles and opportunities available.

Three hour long interview with manager, director and partner. Series of the same questions by each executive. Very redundant. The interview could have been completed within 45 minutes with only one interviewer. For this position, in particular, the interview could have been completed over the phone.
