Not sure if it's best, but I try to identify a specific area of two within commercial law that I'm really interested in, relate it to my own experiences and try to make parallels focussing on transferable skills, and then link it to the firm.When answering motivation questions about commercial law, so "why commercial law" and "why do you want to be a commercial lawyer", how exactly can you demonstrate clear, genuine interest and motivation without sounding forced or cliche?
