Yeah, they must've changed it up a bit this year.
It was very much centered on my application and what I'd written about. They didn’t ask any competency/strengths questions but I would still be sure to have them ready to go.
The firm has such a huge focus on culture and understanding what they’re about so try to be personable and build rapport if you can. Additionally, remember the things that make them stand out (free-market system, strengths across both transactional and contentious work, fearsome foursome etc.)
Good luck with the interview! Hope this helps and let me know if you have any other questions.
