Concepts to Revise
Based on the questions on this page, these are the areas most worth revising.
Apex
- Governor limits for SOQL, DML, CPU time and heap size
- Bulkification: no SOQL or DML inside loops
- Sharing keywords and how they affect record access
- Asynchronous Apex: future, queueable, batch and schedulable
- Test classes: test data, System.assert, Test.startTest and Test.stopTest
- Collections and wrapper classes
Triggers
- Context variables: isBefore, isAfter, isInsert, isUpdate, isDelete, isUndelete
- Trigger.new, Trigger.old, Trigger.newMap and Trigger.oldMap, and in which events each exists
- One trigger per object with a handler class
- Preventing recursion with static variables
- addError to block a save with a message
- Testing triggers with single and bulk records
Integration
- REST versus SOAP and when to use each
- Named Credentials and external credentials
- HttpRequest, HttpResponse and callout mocks
- Platform Events and Change Data Capture
- OAuth flows and Connected Apps
- Apex REST with @RestResource
How to Prepare
The questions on this page lean towards Apex, Triggers and Integration. Spend most of your revision time there, then cover the remaining topics lightly.
- Practise explaining governor limits and bulkification with a real example from your own project.
- Write a trigger with a handler class from memory, then test it with 200 records to prove it is bulk safe.
- Know one integration end to end: authentication, callout, error handling and testing with a mock.
- Say your answers out loud. Interviewers listen for clear, structured explanations, not memorised definitions.
- Prepare one or two real examples from your own projects for the general questions.
