Here is what rjessome, an immigration consultant, posted on another thread:
When the application reaches the visa office it goes to data entry first. Then to storage, then to the paper screen officer, then recommendations given/instructions made, then back to storage, then checked on the BF date by admin staff to follow up on recommendations/instructions, then if a decision is recommended or further instructions required, forwarded to a VO for a review and either a decision or an interview, then back to storage, and then assigned to a VO on the morning of the interview, then decision entered or stored until the VO gets to it, then to the program manager or senior officer for review of the decision.
