Just putting my own 2 cents into this debate - if I was you I would speak to the graduate recruitment about this concern - hopefully they will clarify any questions you may have. How are you doing your research btw? Are you actually attending law firm events or just basing it off a firm’s website?
I am saying this because I think black candidates have become the most successful over the years when securing TC offers. I have many black friends who are current trainees and hold future trainee titles in elite international law firms, US firms and MC firms. I am a bit baffled on what firms you are looking at that consist of no black people. As I am sure there is some black people at “these” firm, but as
@Jessica Booker mentioned many choose not to showcase themselves, and this is absolutely true. At speak panel events or open days I have attended at many law firms, most or all speakers tend to be white and not of ethnic-minority or black, it doesn’t “automatically” mean that the whole firm is white. You need to research a bit deeper because I think most firms are recruiting a large volume of black people or ethnic minorities now. So you shouldn’t be discouraged at all from applying to any firm you think has 0 black people in it, you are only limiting your own chances
Also you just need to look at LinkedIn and see how much black partners, associates, trainees and future trainees they are!!
