Meesho Frontend SDE Interview Experience

Overview

This document outlines the interview experience for a Senior Software Development Engineer (SDE) candidate at Meesho. The process involved multiple rounds, assessing the candidate's technical skills, problem-solving abilities, and cultural alignment with the company.

Interview Rounds

The Meesho SDE interview process consisted of four distinct rounds:

First Round: Technical Interview

This round focused on evaluating the candidate's fundamental knowledge of JavaScript and frontend engineering principles. The interviewer explored the following areas:

JavaScript Input/Output Mechanics: The candidate was questioned on event loops, asynchronous behavior, and execution contexts.
React Hooks: The interview included practical applications of useEffect, useMemo, and custom hooks.
Virtual DOM & Performance: Discussions centered on React's reconciliation process and rendering optimization techniques.

Hands-on Implementations:

The candidate was required to implement debouncing and throttling from scratch. Emphasis was placed on edge case handling and performance trade-offs.

Second Round: Machine Coding

This round presented a practical coding challenge.

Task:

The candidate was tasked with building a generic, reusable, accessible, and responsive progress bar component in React. The component needed to support dynamic percentage updates, customizable colors and labels, and smooth transitions.

Follow-up Questions:

Component reusability and props design.
Optimization of re-renders.
Styling consistency (CSS modules vs. styled-components vs. Tailwind).

Third Round: Data Structures and Algorithms (DSA)

This round assessed the candidate's problem-solving abilities and knowledge of data structures and algorithms.

Problem:

Array Intersection: The candidate was asked to return the intersection of two arrays with optimal time and space complexity. The solution involved a hash map approach, with attention to edge case handling for duplicates and large input sizes.
