Universal Containers has two custom objects: Job and Job Interview. The Job Interview object has a lookup relationship to Job. Both objects are set to Private in sharing settings. The HR team will own all Job and Job Interview records. They have asked their Salesforce Architect to automatically share the Job Interview when the Interviewer (lookup to user record) has been populated. The interviewer can be from any department. What method should the Architect use to achieve this requirement?

Universal Containers (UC) has a private Organization-Wide Defaults (OWD) model for the Account object and needs to control the access of records and fields according to these requirements:
* Sales reps can view/edit only their own records and cannot access the field "segment" in account page.
* Service reps need to view all accounts but cannot edit any information.
* Sales managers can modify any account of reps reporting to them.
* Service managers can modify any account.
How can a Salesforce architect provide an optimal solution for this scenario?
