React Interview Experience (Dec 2025): Sprinklr

Overview

In December 2025, a frontend developer candidate participated in Sprinklr's interview process for a frontend developer position. The first technical round stood out as a pure hands-on React machine coding challenge, offering valuable insights for developers preparing for product-based company interviews.

The interview environment was structured around practical coding exercises conducted in an online IDE similar to CodeSandbox, focusing on real-world frontend development skills rather than traditional algorithmic puzzles.

Interview Process

Sprinklr's frontend interview process emphasises practical React development skills. The technical assessment comprised a single round with two distinct coding challenges, each designed to evaluate different aspects of frontend engineering:

• Question 1: A logic-focused implementation with pre-designed UI, testing component architecture and state management
• Question 2: A full-stack implementation requiring both UI design and functionality, testing creative problem-solving and frontend craftsmanship

This balanced approach allowed the interviewers to assess both the candidate's ability to work within constraints and their capacity for independent design decisions.

Technical Rounds

Round 1: React Machine Coding

The machine coding round consisted of two comprehensive React challenges. Both questions were designed to test React fundamentals and component-based thinking.

Question 1: Infinite Nested Folder Structure

The first challenge required building a nested file-folder interface, similar to the sidebar navigation in VS Code.

Requirements:

• Each folder could contain unlimited subfolders or files
• Each node required "Add File" and "Add Folder" buttons with an input field for naming
• Pressing Enter would add the new item to the structure
• Each node needed a "Delete" button that would remove the item and all its children (for folders)

Technical Concepts Tested:

• Recursive component creation in React
• Tree data structure manipulation and immutability principles
• Efficient nested state updates without mutation
• Props drilling and handler function design

Implementation Approach: The candidate implemented a recursive <Folder /> component architecture, passing add and delete handlers through props. The key challenge was maintaining immutable state updates whilst traversing the tree structure. The pre-designed UI allowed the candidate to focus entirely on logic implementation and component composition.
