5.22Interview scenario
Find Contacts belonging to active enterprise Accounts.
Assume Account fields:
Status__c
Customer_Tier__c
Then:
SELECT
Id,
FirstName,
LastName,
Email,
Account.Id,
Account.Name
FROM Contact
WHERE Account.Status__c = 'Active'
AND Account.Customer_Tier__c = 'Enterprise'
That's a very realistic integration query.
