Hi rtrave2, my interview consisted mainly of the final competencies listed on the pwc site.
He asked questions like tell me how you build relationships, when you learnt something new and how i went about it, how i would manage work with other personal activities, a time when i delivered good customer service.
I wasn’t asked why pwc, but i made sure to tell him and i wasn’t asked commercial awareness questions but i mentioned recent issues in passing which showed him i was up to date.
The partners are really good and making you feel easy and comfortable and so long as you keep enthusiastic you should be fine.
All the best
