Huge congratulations on the TC offer - that's a fantastic achievement! 🎊I’ve received a TC offer for an up and coming US firm with a smaller trainee cohort (under 10). It’s a large firm with many offices however the London office isn’t the biggest out of US firms in London. Its training is ranked A in legal cheek. What are the benefits and disadvantages of accepting an offer from this firm - will it become a hindrance upon qualification if I wanted to move to a larger firm?
Joining a smaller trainee cohort can actually be a real advantage. You'll likely get more hands-on responsibility, closer supervision, and better exposure to quality work early on. The fact that the firm's training is ranked highly is also a strong indicator that you'll be well supported and develop quickly.
The potential downsides are mainly around scale - a smaller London office might mean fewer seat options and a leaner support network. Brand recognition might also not be immediate as the biggest US or Magic Circle firms, but solid training and good deal experience tend to matter much more in the long run!
Overall, it doesn't sound like it would be a hinderance at all - if anything, the quality of training and the exposure you'll get could make you a very well-rounded candidate on qualification. I would just make sure the firm's practice areas and culture align with what you want long term.
Best of luck with your decision - either way, you should celebrate receiving such an amazing offer!
