Salesforce Developer Interview Questions – 2025 Best
That feeling right before a Salesforce developer interview is unique. Your palms are sweating. You’ve crammed information for weeks. You’re wondering if you’ll remember what a trigger does under pressure. Worse, you’re unsure which questions might come up and how deeply they’ll test your knowledge.
Here’s something that helps immensely when preparing candidates for Salesforce interviews: interviews are not random. Hiring managers ask similar questions repeatedly because they are assessing specific skills. Understanding these patterns and preparing accordingly transforms anxiety into confidence.
I have conducted dozens of Salesforce developer interviews and guided hundreds of candidates through preparation. The reality is simple: most people fail not because they don’t know Salesforce, but because they don’t understand what interviewers are really asking or the depth of knowledge expected at different experience levels.
Let’s break this down clearly.

Understanding Interview Expectations by Experience Level
This is the most critical context candidates often miss. Freshers, mid-level developers with 2–3 years of experience, and senior developers with 5+ years all interview on the same Salesforce platform but the depth and complexity change dramatically.
Fresher-Level Expectations
Fresher interviews focus on foundational understanding. Can you explain what a trigger is? What is the difference between a batch Apex class and a queueable class? Do you understand basic object-oriented programming concepts?
The bar is intentionally lower. Companies expect to train freshers. They are evaluating learning ability and conceptual clarity more than advanced expertise.
Mid-Level Developer Expectations (2–3 Years)
At this stage, expectations rise significantly. You are expected to handle complex logic independently. Interviewers ask about design patterns, performance optimization techniques, and real troubleshooting scenarios.
They want proof that you’ve solved real-world problems not just textbook exercises.
Senior Developer Expectations (5+ Years)
Senior-level interviews set the highest bar. Questions focus on architecture decisions, system design, scalability, governance, and mentoring junior developers.
You’re evaluated on strategic thinking and your ability to make technical decisions that impact the entire organization.
Understanding where you stand helps you prepare accurately. Over-preparing beyond your experience level creates stress; under-preparing wastes opportunity.
Core Technical Questions Every Salesforce Developer Faces
Certain questions appear in nearly every Salesforce interview, regardless of experience level. Your answers must be clear, confident, and practical.
Difference Between Trigger and Workflow Rule
This question tests your understanding of Salesforce automation. Your answer should explain trigger flexibility, workflow rule limitations, and real-world use cases not just definitions.
What Are Governor Limits and Why Do They Exist?
This assesses your understanding of Salesforce’s multi-tenant architecture. Explain why limits exist, provide examples, and describe how you design code to stay within limits.
Difference Between SOQL and SOSL
SOQL queries records from a single object or related objects, while SOSL searches text across multiple objects. Knowing when and why to use each is critical.
Salesforce Security Model and Development Impact
This question evaluates architectural thinking. Discuss organization-wide defaults, role hierarchy, profiles, permission sets, and how security affects your development approach.
These are not trick questions. They test depth of understanding, not memorization.
Scenario-Based Questions That Separate Strong Developers
This is where experienced developers shine. Interviewers present real-world problems and evaluate your thought process.
Example Scenario: A trigger calls a web service for a custom object with thousands of records, and failures have started occurring intermittently.
Strong answers explain debugging methodology: checking governor limits, reviewing logs, considering asynchronous processing, batching, and error handling.
Another common scenario involves real-time integration with external systems without exceeding API limits. Discuss platform events, batch processing, integration patterns, and monitoring.
Your logic matters more than the final answer. Ask clarifying questions. Explain your approach. Stay calm.
Questions on Best Practices and Code Quality
Interviewers increasingly value maintainable and scalable code.
Testing Approach
Explain how you write test classes, cover edge cases, mock callouts, and ensure long-term reliability. Mention CI/CD practices if applicable.
Code Reviews
Discuss reviewing for security risks, performance, readability, and coding standards. Show that you value collaboration and quality.
Error Handling Strategy
Explain try-catch usage, logging mechanisms, user-friendly error messages, and system stability.
These questions distinguish developers who write code that merely works from those who write code that lasts.
Experience-Level Deep Dive Questions
- Freshers: Learning challenges and how you overcame them
- Mid-level: Complex projects you handled independently
- Senior-level: Designing scalable systems and mentoring strategies
Each level tests growth, impact, and responsibility.
Behavioral Interview Questions
Technical skill alone isn’t enough. Expect questions like conflict resolution, failures, and teamwork experiences.
Be honest. Demonstrate communication skills, adaptability, and learning mindset.
Preparation Resources and Practice Strategy
Study official Salesforce documentation, especially developer and API guides. Create a structured preparation plan covering fundamentals, scenarios, and mock interviews.
While GTR Academy is primarily known for SAP enterprise training, its structured, hands-on learning approach reflects what successful Salesforce preparation also requires methodical learning combined with real practice.
Participate in mock interviews and Salesforce communities to receive feedback.
Interview Day Strategy
The day before, revise core concepts lightly. Avoid learning new topics. Rest well.
During the interview, listen carefully, pause before answering, and explain your thinking clearly. Asking clarifying questions shows professionalism.
