Two phone calls, case, final in-person. They were very nice and supportive, and everything was straightforward. I was offered a position 5 days after the final round. It was all very well done.
I applied online. The process took 6 weeks. I interviewed at PwC (Londres, Inglaterra) in Feb 2014
Interview
It was straightforward. Exactly what I expected. Competency based. Useful to remain friendly and approachable throughout the interview. Being concise helped. And reading up on the organisation's current work - whatever they were in the news for - also helped.
I applied online. I interviewed at PwC in Nov 2015
Interview
Submit online profile, then complete online tests. Within 5 minutes of completing the online tests, was told they would not like to proceed further with my application; did excellent on the numeracy and personality sections, but only average on the logical reasoning section.
A bit curious why they don't do the tests first, if that portion is entirely automated and seems to have the bulk of the weight. Unlike other firms, I discerned no human component between your filling in profile information, CV submission and answering short questions about 'Why PwC' (i.e. you can complete the tests ASAP, and feedback is also, as mentioned, ASAP)
