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
Lightning Web Components
- Lifecycle hooks: constructor, connectedCallback, renderedCallback, disconnectedCallback
- Decorators: @api, @track, @wire and when each is needed
- Parent to child and child to parent communication using properties and custom events
- Lightning Data Service and the uiRecordApi functions
- Calling Apex: wire versus imperative, and cacheable methods
- Template directives: if:true, for:each, key and lwc:if
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
How to Prepare
The questions on this page lean towards Apex, Lightning Web Components and Triggers. 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.
- Build one small component that uses @wire, an imperative Apex call and a custom event, and be ready to explain each part.
- Write a trigger with a handler class from memory, then test it with 200 records to prove it is bulk safe.
- 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.
