Narrative:

This event is the second time in the last month where norcal final approach into oak ILS30 places aircraft too high for ILS intercept (arriving from north; right downwind). The glideslope commands a descent prior to localizer intercept. Once the aircraft is established; it becomes a struggle to get down and re-stabilize. As an example; both times; the workload was so intense that the FAF was not verified and crosschecked. Time and frequency congestion have limited the ability to request lower (prior to intercept). Although both approaches met the stable criteria; I believe that tight and high vectors contribute to destabilizing an approach.
