I attended the Lumel interview, which had four online rounds.
1st Round – Aptitude
The first round was an aptitude test.
2nd Round – Coding
Two coding problems were given:
Problem 1: Given an array of numbers from 0 to 10, find the missing number.
Problem 2: A word pattern problem, similar to LeetCode:
Example: pattern = "abba"
string = "dog cat cat dog"
Both questions were standard LeetCode-style problems.
3rd Round – Technical HR
In this round, they focused on:
JavaScript interview questions (top concepts)
React questions
HTML & CSS questions
One Sudoku program
One more coding problem (same as problems listed on interview experience websites)
Questions about my projects and resume
4th Round – HR
This was a general HR round with typical HR questions.
