Frequently asked questions
What are the most common Salesforce interview questions and answers?
Most Salesforce interview questions and answers revolve around a mix of admin and developer concepts: standard vs custom objects, lookup and master-detail relationships, profiles and permission sets, OWD and sharing rules, workflow rules and flows, validation rules, SOQL, Apex triggers, and LWC basics. Interviewers also ask scenario-based questions such as automating a business process or designing a data model for a requirement. The best approach is to explain the concept briefly and then support it with a real example from a project or your practice org.
What are the common Salesforce interview questions for freshers?
Salesforce interview questions for freshers usually stay at the fundamentals level: what CRM is, standard vs custom objects, record types, relationships, profiles vs permission sets, workflow vs flow, and basic SOQL queries. You may also get simple Apex questions like what a trigger is or what governor limits are. Interviewers mainly check conceptual clarity, so be honest about your depth, highlight your Trailhead badges and personal projects, and clearly explain whatever you have built in your own developer org.
What are the common Salesforce interview questions for 5 years of experience?
Salesforce interview questions for 5 years of experience go well beyond definitions. Expect deep dives into trigger frameworks and bulkification, asynchronous Apex (Batch, Queueable, Scheduled, Future), order of execution, exception handling, test class strategies, REST/SOAP integrations, security and data model design, and SOQL performance tuning. Interviewers also assess how you handled real project situations, so prepare a few STAR-format stories covering complex requirements, production issues, and deadlines. At this level, architecture decisions and trade-offs matter more than syntax.
What are the most asked Salesforce Apex interview questions?
The most frequently asked Salesforce Apex interview questions cover order of execution, trigger best practices and bulkification, governor limits, SOQL and SOSL, asynchronous Apex (Future, Queueable, Batch, Scheduled), exception handling, test classes and code coverage, and integration using REST API callouts. Many interviewers also ask you to write a trigger or a SOQL query live. Practicing actual coding in a developer org is essential, because explanations alone rarely clear Apex rounds.
What are the common Salesforce Apex trigger interview questions?
Common Salesforce Apex trigger interview questions include the difference between before and after triggers, how to write bulkified triggers, how to prevent recursive trigger execution, when to use a trigger vs a flow, and how to design a trigger handler framework. You should also be comfortable explaining the full order of execution, since trigger questions almost always connect to flows, validation rules, and other automation. Writing a clean trigger for a live scenario, like updating related child records, is what interviewers usually expect.
What is Apex in Salesforce?
Apex is the primary Salesforce development language — a strongly typed, object-oriented language with Java-like syntax that runs natively on Salesforce servers. It is used to write triggers, custom classes, batch and scheduled jobs, web services, and custom business logic that point-and-click tools cannot handle. Since Apex runs in a shared multitenant environment, it operates under governor limits that cap things like the number of SOQL queries per transaction, which is a major interview topic in itself.
What is LWC in Salesforce?
LWC (Lightning Web Components) is Salesforce's modern framework for building user interfaces on the Lightning Platform using standard web technologies — HTML, CSS, and modern JavaScript. It is lighter and faster than the older Aura framework and is now the preferred choice for custom UI development. In interviews, common LWC topics include the component lifecycle, @api, @track and @wire decorators, parent-to-child and child-to-parent communication, and when to choose LWC over Aura.
How to learn Salesforce development from scratch?
Start with admin basics — objects, fields, relationships, security, and automation — because Salesforce development sits on top of them. Use free Trailhead trails and a free developer org, then move to SOQL, Apex classes and triggers, test classes, and finally LWC. Build 2–3 small projects end to end, such as an approval app with custom triggers and a Lightning UI. Learning in this order keeps everything practical and gives you concrete work to show in interviews.
How to become a Salesforce developer?
The usual path is to learn admin fundamentals first, then Apex, SOQL, and LWC through Trailhead and a free developer org, build a small portfolio of projects, earn the Platform Developer I certification, and then apply for fresher or junior roles through LinkedIn, Naukri, referrals, and Salesforce consulting partners. With consistent daily effort, most people become job-ready in around 6–12 months. Hands-on project work matters more to hiring managers than certificates alone.
How to find Salesforce developer jobs in India as a fresher?
Start by earning Platform Developer I or building strong Trailhead credentials, and prepare 2–3 portfolio projects you can demo. Apply through LinkedIn, Naukri, and Indeed, and target Salesforce consulting and implementation partners, since they hire freshers in volume. Referrals from Salesforce communities and local developer groups significantly improve shortlisting. Because most fresher Salesforce developer jobs screen on basics plus problem-solving, practice Apex trigger and SOQL questions and do a few mock interviews before applying widely.
What is the average Salesforce developer salary in India?
Salesforce developer salary in India depends heavily on experience and skill depth. Freshers typically start around ₹4–7 LPA, developers with 3–5 years of experience commonly earn ₹10–18 LPA, and senior developers with strong Apex, integration, and LWC skills can cross ₹25 LPA, especially in product companies and large consulting firms. Certifications like Platform Developer I and II, combined with real project experience, directly influence the offers you receive.
Do I need a paid Salesforce development course to become a Salesforce developer?
No — a paid Salesforce development course can speed things up with structure and feedback, but it is not mandatory. Trailhead is free and covers everything from admin basics to Apex and LWC, and a free developer org gives you unlimited practice space. Employers test hands-on ability, so self-learners who build projects and practice interview scenarios do just as well. If you struggle with consistency or want code and interview feedback, a mentor or guided program usually helps more than a pre-recorded course.
How to create a free Salesforce Developer Edition org?
You can sign up for a free Salesforce Developer Edition org on Salesforce's official developer website using just an email address — it is free for life and includes Apex, LWC, SOQL, and most standard features for practice. It is meant for learning and development only, so it cannot be used as a production org, and a few advanced features are restricted. Log in at least once every few months to keep it active, and start coding with the Developer Console or VS Code with Salesforce extensions.
Which is the best Salesforce Apex guide for interview preparation?
For fundamentals, Salesforce's official Apex documentation and Trailhead's Apex trails are the most reliable starting points because they are updated with every release. For interviews specifically, choose a Salesforce Apex guide that covers order of execution, triggers with working code examples, asynchronous Apex, SOQL, exception handling, and test classes — theory alone is not enough for Apex rounds. Whichever guide you use, pair it with regular coding practice in a developer org, since most interviews include live coding or a scenario-based task.
