Most Salesforce interview questions for freshers focus on platform fundamentals: standard vs custom objects, profiles vs permission sets, record types, lookup vs master-detail relationships, OWD and sharing rules, and when to use Flow over Apex. You may also be asked to write a simple SOQL query or explain a basic trigger. Prepare short, real examples for each concept, because recruiters in India consistently value answers backed by hands-on practice over textbook definitions.

At the 5-year level, interviews shift from definitions to scenarios. Expect questions on bulkification and governor limits, asynchronous Apex (Batch, Queueable, Scheduled), trigger frameworks, integration patterns (REST/SOAP, Named Credentials), security (CRUD/FLS), LWC, and deployments using Change Sets, SFDX, or CI/CD. Interviewers often present a business problem and evaluate how you design the solution, so practice explaining your project decisions end-to-end.

Senior interviews focus on architecture and leadership: designing single-org vs multi-org strategies, large-scale data migrations, integration architecture, performance and scalability, security model design, DevOps and release management, and declarative-vs-code trade-offs. You should also prepare behavioral answers on mentoring teams, gathering requirements, and managing stakeholders, since 10+ year roles usually carry solution design responsibility.

Salesforce testing interview questions usually cover the testing types used on the platform — Apex unit testing with assertions, integration testing, UAT, regression and security testing — along with test data creation using @testSetup, SeeAllData restrictions, code coverage requirements for deployments, and testing Flows and LWC components. QA-focused roles also get scenario questions on testing triggers, automations, and integrations.

LWC (Lightning Web Components) is Salesforce's modern framework for building user interfaces on the platform. It is built on standard HTML, CSS, and modern JavaScript, which makes components lighter and faster than the older Aura framework. LWC uses wire adapters and Lightning Data Service to read data reactively, decorators like @api and @wire, and is used to build custom record pages, app pages, and Experience Cloud sites.

Frequently asked LWC questions include lifecycle hooks (connectedCallback, renderedCallback, disconnectedCallback), @api, @track and @wire usage, parent-to-child and child-to-parent communication with custom events, Lightning Message Service, calling Apex imperatively vs with @wire, conditional rendering, iteration with for:each, and Lightning Data Service. Interviewers often ask you to build or explain a small component scenario rather than only give definitions.

Begin by strengthening HTML, CSS, and modern JavaScript (ES6 concepts like arrow functions, promises, and modules), since LWC is built on web standards. Then learn the component structure, decorators, and lifecycle hooks, set up VS Code with the Salesforce Extension Pack, and build small hands-on components — a record display card, a custom form, a search-and-filter list. Working through real mini-projects is what turns LWC basics into interview-ready skill.

Enable Debug Mode for your user in Setup so LWC code appears readable in the browser, then use Chrome DevTools for console logs, breakpoints, and the network tab to inspect Apex callouts. console.log() statements, checking the rendered component tree, and reviewing @wire adapter errors are the most common debugging steps. In VS Code you can also debug Apex and run LWC Jest tests to validate component logic.

Apex triggers are pieces of code that automatically execute when records on an object are inserted, updated, deleted, or undeleted. They run in before events (used to validate or modify the same record) and after events (used to work with related records or additional logic). Triggers are the standard way to implement complex automation that declarative tools like Flow cannot handle, and interviewers expect them to be bulkified and written within governor limits.

These are interview questions that describe a real business problem and ask how you would solve it with a trigger — for example, preventing duplicate account creation, updating child records when a parent changes, restricting an opportunity stage change unless conditions are met, or blocking deletion of a record with related opportunities. Working through Apex triggers practice examples like these trains you to handle bulk data and context variables correctly, which is exactly what interviewers assess.

Follow one trigger per object, bulkify your logic so it works with up to 200 records, never place SOQL queries or DML statements inside loops, delegate logic to a handler class, avoid hard-coded record IDs, and use context variables correctly. Writing test classes that cover both single-record and bulk scenarios, and documenting the trigger's purpose, are also considered must-have practices in code reviews.

You cannot delete a trigger directly from the production UI. The safe approach is to first deactivate the trigger, confirm nothing breaks, and then remove it from your source and deploy the deletion through a change set, SFDX, or the Metadata API from a sandbox. Removing triggers without a proper deployment path is one of the most common mistakes teams make in production orgs.

In current Salesforce releases, users with the right permissions can deactivate a trigger directly from Setup by opening Apex Triggers and changing the trigger's active status. If that option is unavailable in your org, deploy a version of the trigger marked inactive from a sandbox using a change set or metadata deployment. Deactivating is safer than deleting because you can reactivate the trigger quickly if other automation depends on it.

A trigger framework is a structured design approach that keeps trigger logic organized — typically one trigger per object that immediately hands off to a dedicated handler class instead of containing business logic itself. Frameworks make it easier to control execution order, bypass logic during data loads, prevent recursion, and unit test the code. For anything beyond simple automation, developers are expected to know and apply at least one framework.

The handler pattern is the most widely used trigger framework: the trigger itself contains only a single call to a handler class, such as AccountTriggerHandler, which defines separate methods like beforeInsert(), afterUpdate(), and beforeDelete(). This separation makes the logic reusable, testable, and easy to extend, and a static flag in the handler is typically used to control recursion. Interviewers often ask candidates to sketch this structure during scenario rounds.
