Hey all,
Just adding my 2c here - I am a career-changer and I have secured a TC in my first cycle of applications. It can of course be done!
If you have any specific questions, feel free to fire them over. I think what the recruiters were most interested in my end was "Why Commercial law now?" That is going to be a critical question that you must be able to answer and answer persuasively. For me, I was helped by the fact that I had begun studying law at undergrad, had a quasi-legal background (Police) and had engaged with the commercial side of the law through the start of my studies (open days, first-year schemes, etc).
You will be surprised how attentive recruiters are to your profile. Often, they get a lot of candidates who have a similar profile to each other and I'm sure (caveat: I am not a recruiter) asking the same questions over and over again may be a little mundane. So, I expect they enjoy asking and hearing about different things!
My one tip is to not take your career-changer status and professional background for granted. I can assure you, you will gain no leverage from this position. Everything you will need to achieve will be on merit, so, put in the work with applications, ace the interviews, and success will be yours
