Goldman Sachs corporate derivatives (IBD, not equity deratives in S&T)

I understand this Group sits alongside the other IBD teams (cap markets, M&A) and hedges risk (through fx, interest rates, etc.) resulting from an underlying transaction (like a bond issue or a merger).

My questions are:

1) Is the group mainly traders and structurers who trade on behalf of a client following a M&A or a DCM/ECM deal? How is it different to the actual trading desks that do trades for the bank's clients? I think the Group used to be part of Securities until it was moved into IBD a few years ago?

2) How's this group viewed within the bank? I understand it's front office, but is it "second fiddle" to the IBD team executing the main deal? (I realise this may be completely misplaced).

3) Any experience on hours, comp, etc?

Thank you.
