Well, I had wished after my interview with a Big4 that I would have gone with the agency. But simply, because they had quite some feedback from candidates who went through the same interview process and even new something about the case studies. I was in touch with them about another role and they knew of my interview with that firm, they even promised to give me some info. But, even after chasing them a few times, nothing happened. Not only that, as soon as my interview was over, they approached me, how it went and asked about the case studies. To my astonishment, they heard it all before, but wouldn't think of helping someone with whom they simply couldn't earn a penny....
