I applied through college or university. The process took 3 days. I interviewed at OYO (Nueva Delhi) in Sep 2021
Interview
It consisted of two technical rounds which tested the candidate's knowledge in data structures and basic computer programming concepts like Object Oriented Programming Language, Database Systems, etc. Some questions based on the projects mentioned in your resume might also be asked.
Interview questions [1]
Question 1
You are given an m x n grid where each cell can have one of three values:
0 represents an empty cell,
1 representing a fresh orange, or
2 representing a rotten orange.
Every minute, any fresh orange that is 4-directionally adjacent to a rotten orange becomes rotten.
Return the minimum number of minutes that must elapse until no cell has a fresh orange. If this is impossible, return -1.
