Apex Triggers - 15 (Amazon Interview Question)

  1. Scenario Overview This automation solves an Amazon Interview Question based on a parent-child relationship between a parent object, Tax_Firm__c , and a child object, Employee__c . The parent features two currency fields: Max_Salary__c and Min_Salary__c . The system must dynamically recalculate and roll up the highest and lowest employee salary values to these parent fields whenever any child employee record is inserted, updated, deleted, or undeleted . Additionally, the solution handles the edge case where all related employees are deleted from a firm, safely resetting the parent summary values to zero instead of leaving stale metrics behind . or Show the Min & Max Salary of Employee records on the Parent Company record. 2.

Apex Handler Class java public class OpportunityTriggerHandler { public static void updateMaxOpportunityName ( List < Opportunity > newOpps , Map < Id , Opportunity > oldOppMap ) { Set < Id > accountIds = new Set < Id >(); // Phase 1: Track all impacted Account IDs acros...
