RobertI also attended a PA assessment day recently and my experience was far more pleasant than Jill's! I've heard from a couple of friend's who have been through PA's process that it is pretty good and relaxed so her bad experience was probably a one-off.It was challenging but not in any way aggressive. I met a good mix of people from the business who were all very nice and got to ask a lot of questions.You'll do 3 things on the day - - interview with someone fairly senior, quite similar to the 1st interview with HR & not technical- individual case study, tight for time and you have to do a role play at the end of it which was the toughest part- group case study, involves some number crunching but considering it is a GROUP assessment I'm guessing the numbers don't matter - they'll be looking at how you work with the other people in the roomOverall, less strenuous than other assessment centres I've been to. Unfortunately I didn't get through to next stage but still had a pleasant experience & got some good feedback from HR afterwards.Hope this helps & good luck!
