Check the PwC 2017 forum on Wikijobs regarding the AC and final interview.
My Advice:
Practice the numerical and logical tests online, i used the free ones. Skip any questions you dont know and dont guess. I got through about 16 questions and answered 13 or 14. I got 3/6 in my feedback call.
You have to finish the written task and you dont have to read all the information.
I got 3/6 in my feedback call.
For the group exercise, be clear and concise when explaining your proposal dont talk for too long. Ask questions that help the group narrow down the proposals which shows youre trying to lead your group to come to a conclusion e.g. Do we think profit is more important or maintaining our relationships with current clients?
Volunteer to explain your proposal first, use names, dont talk over people.
I made a calculation error in the group ex but still passed.
Final Interview:
Prepare examples for the 5 competencies, 2 or 3 examples for each.
Know about your service line.
Go in with some commercial awareness

Prepare answers to motivational questions.
