Too Early to go to the Buyside?

Hey guys,

Wanted to hear some opinions on my situation. I am about to wrap up my first year in M&A in London at a mid-market BB (good team). I am not burnt up or anything, but definitely I could do without working the hours we all do and the shitty lifestyle that comes with IB. I'd actually say overall I am doing better mentally than many other in position.

Here comes my question: I am advanced in a process to go work at a big HF (equities L/S multi manager) in the same sector I currently cover. If it turns into an offer, I could be out of IB after one year on the job. I definitely came in with more experience than most others (I interned 6 months at a MM PE fund and 6 months at a shit IB) but I feel like I would be leaving on the table a lot of learning, especially when it comes to attention to detail which is definitely not my strong suit.

Do you think being a junior at a HF would help me on this skill to a similar amount? What are the chances I regret moving because I start growing less (or in a different direction) than I would in IB? I definitely want to work in a position like that in the long term, however I am a bit worried it might be too early. Flipside is I might not get the opportunity again

Thanks!
