I always thought Sydney orders 3 mandatory clearances (FOSS, RCMP and CSIS) and does file triage based on pre-RQ indicators, i.e. based on just info in application form, not investigations.
Local office can reorder clearances in case of expiration (1 year after obtaining clearance) and takes more personal approach with file.
As you can see from a
file requirements checklist (a form stored with your file and filled by agents, officers and judges during a case progression), there's job to be done before interview by local office, including following up on triage done in Sydney and checking some systems as FOSS and GCMS again (which I suspect not equals to full clearances, but checking for new notes via some kind of service/terminal). Also, there are reports of agents accessing LinkedIn profiles before interview, so they're "googling" you too. That's what they have to complete in local office:
=> PART B (to be completed by local office)
