Interview process has several stages. FIrst, standard online tests. Next phone interview asking pretty predictable competency questions, and why kpmg, why tax etc? Then assessment day, this is interesting because it doesn't involve any group exercises but is rather quite individual focussed. You are pretending to work for an energy company and throughout the day do various activities. This includes a written report making recommendations, an e-tray and some simulated meetings with actors. My actor was quite weird and started interviewing me half way through, although I don't think this is usually the case. Finally partner interview, which was more standard questions and talking through a few different businesses. Of all the parts this felt very relaxed.
