Salesforce developer interviews test the platform's specifics — Apex (its Java-like language), SOQL queries, Lightning Web Components, and the all-important governor limits that shape how you must write code on a multi-tenant platform. Here are the Salesforce developer interview questions that actually get asked.
Apex & governor limits
- What is Apex, and how does it differ from Java?
- What are governor limits and why do they exist?
- Why must you bulkify code, and avoid SOQL/DML in loops?
- Synchronous vs asynchronous Apex (future, batch, queueable).
Data model & SOQL
- Objects, fields, and relationships (lookup vs master-detail).
- SOQL vs SOSL; relationship queries.
- What is the order of execution on a record save?
- Sharing and security — profiles, permission sets, sharing rules.
Triggers & UI
- Triggers — before vs after, trigger context variables, best practices.
- Lightning Web Components (LWC) vs Aura.
- Validation rules, flows, and when to use declarative vs code.
- Test classes — why 75% coverage is required.
How to prepare
Salesforce rounds probe Apex patterns and limits verbally. Practise explaining bulkification and governor limits out loud. Greenroom runs spoken technical interviews that follow up on your reasoning. Pair it with our Salesforce company and OOPs guides.
Frequently asked questions
What questions are asked in a Salesforce developer interview?
Salesforce developer interviews cover Apex and how it differs from Java, governor limits and bulkification, synchronous vs asynchronous Apex (future, batch, queueable), the data model (objects, fields, lookup vs master-detail relationships), SOQL vs SOSL, the order of execution, security (profiles, permission sets, sharing), triggers and best practices, Lightning Web Components vs Aura, and test classes with the 75% coverage requirement.
What are governor limits in Salesforce?
Governor limits are runtime limits Salesforce enforces because it's a multi-tenant platform where many customers share resources — for example, limits on SOQL queries (100 per transaction), DML statements, CPU time and heap size. They prevent any single process from monopolizing shared resources. Developers must write efficient, bulkified code that stays within these limits, which is a core Salesforce skill.
Why do you need to bulkify Apex code?
Bulkification means writing code that processes many records at once rather than one at a time, because triggers and operations can fire on batches of up to 200 records, and governor limits cap how many SOQL queries and DML statements you can run per transaction. Placing SOQL or DML inside loops quickly exceeds limits, so you query and update collections in bulk outside loops instead.
How should I prepare for a Salesforce developer interview?
Master Apex, governor limits and bulkification, the data model and relationships, SOQL, triggers and Lightning Web Components, and know when to use declarative tools versus code. Practise explaining bulkification and governor-limit-safe patterns out loud with a voice-based mock interview that follows up, since these platform-specific concepts are the core of Salesforce developer rounds.
