I find you often have to look beyond the firm's website. In my experience many websites seem outdated and actually provide minimal information on their deals, cases and recent updates.How can I prepare for a 'tell us about a recent deal' interview question? The firm doesn't have a huge amount of detail on its website.
Try looking on The Lawyer, Global Legal Post, Legal 500 for recent cases/clients. I also find a really useful resource is the firm's LinkedIn page, as partners/fee-earners will often post details about their work and provide interesting opinions! Once you have found the deal/case, you can then look online more generally at the companies, sectors and jurisdictions involved.
Hope that helps!
