When performing large-scale changes, such as reorganizing roles or reassigning ownership, recalculating sharing rules can be resource-intensive and may affect performance. Deferred Sharing Recalculation allows Salesforce admins to temporarily pause sharing rule calculations during bulk operations. This ensures that the reorganization completes efficiently, and the sharing recalculations are processed after the changes are made.
* Option A: Partitioning data using Divisions helps segment data logically but does not address the specific need to optimize sharing recalculations.
* Option B: Skinny tables improve query performance for specific data structures but do not mitigate recalculation delays.
* Option C (Correct): Deferred Sharing Recalculation ensures minimal performance impact during bulk ownership changes or Role Hierarchy updates.

Explanation
According to this source, Apex managed sharing is the best way to share records based on complex logic that can't be handled by declarative sharing. In this case, the architect can use Apex code to create a trigger on the Job Interview object that will create a share record for the interviewer user when the lookup field is populated.
The other options are not feasible or scalable.

Explanation
The OWD for pricebook should be set to Use, which means that users can only view and use price books that are shared with them. This way, sales agents can have access to products and create opportunities for their customers. Option A is incorrect, since Public Read Only would give access to all price books to all users.
Option B is incorrect, since Public Read Write would give access and edit rights to all price books to all users.
Option C is incorrect, since View is not a valid OWD setting for pricebook.
