Salesforce Interview Questions and Answers
122 Interview questions
A primary key is a unique identifier for a record in a database table, ensuring data integrity and enabling efficient data retrieval.
Uniqueness: Each value in a primary key column must be unique across the table.
Non-null: Primary key fields cannot contain NULL values.
Single or Composite: A primary key can be a single column or a combination of multiple columns (composite key).
Example: In a 'Users' table, 'UserID' ...
A view is a virtual table in a database that provides a way to present data from one or more tables.
Views can simplify complex queries by encapsulating them.
They can provide a layer of security by restricting access to specific data.
Example: A view can show only the names and salaries of employees from a larger employee table.
Views can be updated, but not all views are updatable depending on their complexity.
Find the k-th smallest element in a binary search tree (BST) using in-order traversal.
In-order traversal of a BST yields elements in sorted order.
To find the k-th smallest, perform in-order traversal and count elements.
Example: For a BST with elements {5, 3, 8, 1, 4}, the 3rd smallest is 4.
Use a stack or recursion to implement in-order traversal efficiently.
Use two heaps to efficiently find the median in a stream of numbers.
Maintain two heaps: a max heap for the lower half and a min heap for the upper half.
When a new number arrives, compare it with the max of the lower half (max heap).
If it's smaller, add it to the max heap; otherwise, add it to the min heap.
Rebalance the heaps if their sizes differ by more than one.
The median is the root of the max heap if it has mo...
OAuth 2.0 is the best authorization type for integrating Salesforce with Postman, ensuring secure access to APIs.
OAuth 2.0 provides a secure way to authorize access without sharing credentials.
You can use the 'Client Credentials' flow for server-to-server integrations.
For user-specific access, the 'Authorization Code' flow is recommended.
Example: Use Postman's OAuth 2.0 feature to obtain an access token from Sales...
Find the optimized path in an n*m matrix from top-left to bottom-right using dynamic programming.
Use dynamic programming to store the minimum cost to reach each cell.
Initialize a 2D array 'dp' where dp[i][j] represents the minimum cost to reach cell (i, j).
Base case: dp[0][0] = matrix[0][0].
For each cell, calculate dp[i][j] as the minimum of dp[i-1][j] and dp[i][j-1] plus the current cell's cost.
Example: For a mat...

The best encryption algorithm to use for storing passwords in a DB is bcrypt.
Use bcrypt due to its adaptive hashing function, making it difficult for attackers to crack passwords
Bcrypt automatically handles salting, a crucial step in password security
Consider using a high cost factor to increase the computational time needed to hash passwords

Interview Preparation Tips
I appeared for an interview in Feb 2025.
The first round was a coding test on HackerRank that lasted 75 minutes and included three medium-level questions. The second round involved pair coding; a CoderPad link was shared, and you were required to solve a coding question within 45 minutes. The third and fourth rounds were focused on High-Level Design (HLD) and Low-Level Design (LLD), which I was unable to experience as I was rejected in the second round.
