I applied through college or university. The process took 5 days. I interviewed at PwC (Los Angeles, CA) in Oct 2017
Interview
The interviewer read off a sheet of their PwC interview guide with all the questions that should be asked, thought I did well, but guess not. Mostly behavioral with a twist, held a good conversation too, but guess it wasn't good enough.
It is all about sharing their experiences at pwc including overseas secondment opportunities. They will ask you about how you deal with difficult team mates and what you have learnt
I applied online. The process took 2 months. I interviewed at PwC (Hongkong) in Nov 2016
Interview
Group exercise, 10 people as a big group but subdivide 5 people each to two small groups, read the case and do a presentation
