Industry & Product Groups in BB Banks

Hi,

Would like to learn more specifics about individual bulge bracket firm's product groups. Like which product and industry groups are particularly strong at a specific firm in BOA, GS and other BB firms. (I learned GS do not have product groups, all deals handled in industry groups)

I know the typical product groups include M&A, LevFin and Restructuring, ECM, DCM. Common Industry groups include Healthcare, Retail, Industrials, Energy, Natural Resources, Financial Institutions, Real Estate and TMT.

Some BB banks do not have restructuring groups as it's something only MM and boutique firms do.
