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
Security and Administration
- Organization-wide defaults and the role hierarchy
- Profiles, permission sets and permission set groups
- Field-level security and object permissions
- Sharing rules and manual sharing
- Validation rules and bypass techniques
- Record types, page layouts and Lightning pages
How to Prepare
The questions on this page lean towards Apex, Triggers and Security and Administration. 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.
- Draw the sharing model on paper: OWD first, then roles and sharing rules, then permission sets on top.
- 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.
