Having just went through the application process for:
PwC (Got an offer)
KPMG (Got an offer)
Grant Thorton (Got to telephone interview stage)
Ernst & Young (Only passed online tests)
Got a large amount of information from this website regarding these application processes and I would be happy to answer any questions.
Some specifics, all Belfast applications.
