Top 50 Salesforce Developer Interview Questions (2025 Updated)

Posted by Vinay Vernekar 3rd January 2026

A curated checklist of the 50 most common Salesforce Developer interview questions for 2025 — concise answers, scenarios, and best practices to help you prepare.

Why this list matters

Recruiters and engineering teams expect applicants to demonstrate practical knowledge, not just definitions. This collection groups the most frequently asked questions across Admin, Apex, SOQL, LWC, Flows, and Integrations and adds short, actionable answers and real-world scenarios.

What’s included

  • Section 1: Salesforce Basics & Admin (Q1–Q10) — core concepts like Profiles vs Roles, Flow types, and governor limits.
  • Section 2: Apex & Triggers (Q11–Q20) — trigger design patterns, bulkification, recursion prevention, and sample handler patterns.
  • Section 3: SOQL & Database (Q21–Q30) — efficient queries, aggregate functions, FOR UPDATE, and SOQL injection prevention.
  • Section 4: Lightning Web Components (Q31–Q40) — communication patterns, decorators, lifecycle hooks, and wiring Apex into LWC.
  • Section 5: Asynchronous Apex & Integrations (Q41–Q50) — when to use Batch, Queueable, Continuations, REST vs SOAP, and Named Credentials.

Quick sample code

Preventing trigger recursion with a static flag (example):

public class TriggerHandler {
   public static Boolean isFirstRun = true;
}

Best practices & preparation tips

  • Focus on real-world scenarios and system behaviour (bulk operations, limits, async processing).
  • Practice explaining trade-offs: why choose Flow vs Apex, Batch vs Queueable.
  • Prepare a few concise stories: a trigger you built, a complex LWC, an integration you optimized.
  • Write and run unit tests — come to interviews with test coverage and sample code snippets.

Concluding thoughts: mastering these 50 questions helps you speak the language of Salesforce engineering teams — showing both theoretical knowledge and pragmatic, scalable solutions.

Why this matters for admins, developers, and business users: Interview readiness translates to better architected solutions in production. Admins reduce support overhead by using Flows and best-practice configurations; developers deliver scalable Apex and integrations; business users get reliable, performant systems that support decision-making.
