Hi
@FutureTraineeMaybe in my opinion, to do well for this type of question, it matters a lot more how you go about your research and analysis rather than the intrinsic value-add of the topic itself. That is why I would advise you to choose some of the topics where a line of analysis pertaining to impact to the firm's clients makes most intuitive sense to you and about which you think you would be genuinely interested to learn more about. This should naturally lead to you being (i) better informed about the topic, (ii) better able to present your thoughts about it clearly and persuasively; and (iiI) better able to answer follow-up questions and discuss the topic at length, should the partners decide they want to test you on that.
As such, I do not think there is any category among the ones you listed that I would advise you to prioritise ahead of the others. What you should choose will depend on your own preferences, as discussed above, but also on the specific operations of the firm. Different firms will be impacted to a different extent by different developments - i.e. clients of a firm with a heavy tech focus will be significantly impacted by everything and anything going on related to AI, clients of firms with a heavy PE/capital markets focused will care a lot about changes in interest rates and broader economic sentiment, etc.
As for sources, some of the ones that were most useful for me are the following:
- FT News Briefing: as you will likely know, the best all around go-to short podcast to keep yourself updated to news
- BBC Business News and/or Bloomberg Europe: great for more in depth coverage of news, the BBC with more of a UK focus, while Bloomberg with a more financial markets-oriented focus
- Watson's Daily: great for in depth analysis of selected focus; teaches you how to go about commercial analysis
- The Global Legal Post, The Lawyer Podcast, Law, disrupted: great to learn how to connect broader commercial developments with law firms' as businesses + great to learn about how to compare firm's practices and operations
- The FT, The Guardian, BBC, Reuters, and just general Google searches: from time to time, I would use these to research a topic that I was particularly interested in.
