Quick answers to key questions

  • What is CRM? Customer Relationship Management is software and a strategy to manage all interactions with customers, such as leads, sales, support and marketing, in one place.
  • Why Salesforce, and how can a business use it? Salesforce is cloud-based, so nothing needs to be installed, it can be customised without much code, scales with the business and has the AppExchange for ready-made apps. A shop, for example, can track leads, convert them to customers, record orders and handle support cases in one system.
  • Can we update the username of a Salesforce user? Yes, an admin can change it. It must be unique across all Salesforce orgs and look like an email address.
  • Access modifiers in Apex. private (only inside the class), protected (the class and its subclasses), public (anywhere in the namespace or org) and global (visible outside the namespace, for example in managed packages).
  • When do we use global? When the code must be visible outside your namespace, for example in managed packages, and for web services such as @RestResource classes.
  • Can a test class access private methods? Not by default. Mark the private method with @TestVisible and the test class can call it.
  • Types of flows. Screen, record-triggered, schedule-triggered, platform event-triggered and autolaunched flows.
  • Which objects store flow information? For example FlowDefinitionView, FlowVersionView and FlowInterview. You can query them with SOQL to see flows, their versions and running interviews.
  • Cacheable with wire. The data comes from the cache, so it may not be the latest. Call refreshApex on the wired result to get fresh data after a change.
  • What is Account Contact Role? It shows the role that a Contact plays for an Account, such as Decision Maker. On Opportunities, the Contact Role object has the IsPrimary field, which marks the main contact. Only one contact on an Opportunity can be primary.

SOQL examples

// Users whose email ends with gmail.com
SELECT Id, Name, Email FROM User WHERE Email LIKE '%gmail.com'

// Use LIMIT
SELECT Id, Name FROM Account LIMIT 10

// Top 10 oldest records
SELECT Id, Name, CreatedDate FROM Account ORDER BY CreatedDate ASC LIMIT 10

// Top 5 newest records
SELECT Id, Name, CreatedDate FROM Account ORDER BY CreatedDate DESC LIMIT 5

// Cases owned by the current user whose Account is owned by the current user (Apex)
Id me = UserInfo.getUserId();
List<Case> cases = [SELECT Id, CaseNumber, Account.Name FROM Case
                    WHERE OwnerId = :me AND Account.OwnerId = :me];

Method overriding in Apex

The parent method must be marked virtual, and the child method must use override.

public virtual class Animal {
    public virtual void makeSound() {
        System.debug('Some sound');
    }
}

public class Dog extends Animal {
    public override void makeSound() {
        System.debug('Bark');
    }
}
