I didn’t convert after sitting in tax last year too but I think that’s because I was disappointed to be there and maybe that came across.RIP bro, thats arguably the hardest area of law. I sat in tax for a spring vac scheme and didnt convert despite having two years tax working experience. Not to scare you but idk anyone who has got a TC after sitting in tax so prepare yourself and get ready for the challenge. Feel free to message me and i can give you a few pointers.
But I was silly to be disappointed really. This is a 1 or 2 week experience which is so short. It’s not a career in tax and as long as you’re in the right headspace, and not acting like you're disappointed, you’ll do fine.
You can arrange coffee chats with lawyers from the other teams and show your enthusiasm that way. You may even be able to ask for some work from a different team too if you’re ahead of things!
