A leading global provider of CRM and cloud computing solutions, Salesforce is a coveted workplace for tech talent. The Salesforce OA is a make-or-break part of the hiring process, testing coding skills and problem-solvingability. This article unpacks the OA’s key traits, question types, and offers proven prep strategies to help you succeed.
Common Question Types and Solving Strategies
Data Structures & Algorithms
Expect array, linked list, stack, and queue problems focusing on sorting, searching, recursion, and dynamic programming. Emphasize optimal timecomplexity and robust edge‐case handling.
SQL
For some roles, you’ll face SQL queries covering joins, aggregations, subqueries, and data manipulation. Be ready to write clean,efficient SELECT statements.
System Design
Certain positions include system-design questions to assess your ability to architect scalable, reliable systems. Analyze requirements, propose ahigh-level architecture, and address performance, availability, and security.
Example Questions
1. Two-Sum (Algorithms)
Prompt: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. Assume exactly one solution and no element is reused.
// Example
nums = [2, 7, 11, 15], target = 9
// Output: [0, 1]2. Employee-Department Join (SQL)
Prompt: Given tables employees(employee_id, employee_name, department_id) and departments(department_id, department_name), list each employee with their department name.
SELECT e.employee_name,
d.department_name
FROM employees e
JOIN departments d
ON e.department_id = d.department_id;3. Scalable Chat App (System Design)
Prompt: Design a WhatsApp-style chat application. Consider millions of concurrent users, real-time messaging, message storage, and authentication.Outline key components, data flow, and strategies for reliability and security.
