I've worked with other consulting groups-- such as on the successor project after the dust settled on this one-- that were not nearly as bad, so I guess sleaziness varies significantly.
In any case, these were from the the actual consulting arm of Oracle inc. And IIRC, our Associate VP for IT said we shouldn't use both Oracle & Oracle Consulting, but that person was overruled by the VP for IT. I the VP was kept around until the lawsuit settled because it might have been taken as a sign or admission of culpability to fire the VP before that, but shortly after the settlement (which we won, incidentally) that person moved on for "other opportunities".
