Switching from PE to HF

I'm just coming up on a year in large cap PE in London, and have various recruiters / headhunters reaching out about roles at HFs.

I've been a bit frustrated in year 1 by the amount of portfolio / sell-side work we do vs. actual "investing", so it sounds like something that could be appealing but I frankly know almost nothing about the HF world.

Can anyone help me understand the key differences vs. PE in terms of hours / lifestyle, career progression, comp etc. and other factors to consider beyond the obvious things like real-time P&L, pure analysis / investing focus, more variable comp but comes earlier (i.e. no waiting 5 years for carry)?

Thanks in advance
