People were such bullies in certain groups to the extent that, having worked at multiple companies before, it seemed impossible that they worked at "Morgan Stanley" and not "Rikers" Sexual misconduct was swept under the rug/you could be called a liar for reporting it (and if it was recorded anyway too bad, because that's illegal in a bank aka the ultimate Catch 22 and people will not come forward to back you up if you do report it). On the other hand, still record everything you can because there's a weird group mentality (again, in some groups), where people will literally flat out lie and it will be used against you.
Moreover, your group's leader might retaliate and bully you because people lacked emotional control to the extent that it was shocking (like people over 40 with kids).

In general, some people got by by being veterans in a middle office position (aka not revenue generating) so they could do the bare minimum or be completely bad at their jobs and still sort of coast because the nature of the company.
