Worth considering Citadel?

A recruiter is reaching out to me about interviewing with Citadel for a role in their NXT program in NYC.

I’m already a tech lead (E5 going on E6 in half) at FB, 6 yoe, TC $500K and I work around 30-35 hours a week, so it’s pretty chill. Also in NYC.

1) Is it possible for Citadel to beat this TC for this role? Recruiter told me I shouldn’t worry about this.
2) Do they buy out people’s stock? A year ago I got a hedge fund offer that offered to buy out, in cash, my next 2 years of vests as a signing bonus (I joined FB instead). At FB I have ~$280k in shares vesting per year on my current vesting schedule.
3) Is this role any good? What are the expectations, is it remote friendly (ie being able to work remote for a week here and there), is it possible to find good <50h) WLB?

Seriously considering this because I actually really enjoy finance as a subject. I also don’t care about being a tech lead and the stupid ladder climbing, only care about $$ and decent working hours.
