From what I remember hearing about it from some people who took them, it did not seem to deviate a lot from a "normal" commercial law interview, having a mix of motivational, competency, and some situational judgement questions thrown in the mix. Besides this, there were only a few aspects that stood out a bit:
- There seemed to be an expectation for you to have a strong grasp of and interest in PE and leveraged finance; thus, you I would advise you to be prepared to explain in simple terms how PE firms work, how a PE/lev fin transaction looks like, how lawyers assist and value-add in these deals, and how this work differs from other types of transactional work done in big law firms.
- There also seemed to be an expectation to have a strong understanding of PW's market position; as such, you should be able to discuss the firm's particular offering and client base, its strengths and any weaknesses, to draw comparisons with its main rivals, and to also have a view as to the firm's strategy, its risks, and what you see to be future opportunities.
