The AC at PwC includes numerical and logical tests, written report and group discussion. The tests are just roughly the same difficulty level as the online test. The written report is around 30 minutes including the time to read case study, so a bit tense. Most of us wrote for 2 pads. Group discussion conducts in the group of five, there is no presentation. The assessors just watch your performance throughout the who discussion. The tricky thing is that they mix candidates applying for different programmes together, such as summer internship and graduation scheme for different divisions. I think first year students are hence quite at disadvantage.
