Interview
they took online test on hackerrank,they ask some mcq from os and cn ,then shortlist a candidate for face to face interview,basically question based on array and data structure in which we have to work on complexity.question basically to find the frequency of next occuring element.

4. minimum cost path
I applied through university. The process took 2 days. I interviewed at OYO (Gurgaon, Haryana) in Jul 2025
Interview
Began with a test 2 coding ques followed by 2 tech interviews and then hr interview.ques were asked from graph and sliding window slightly molded from the ones at leetcode
2 rounds with DSA where the topic was trees and had to solve the question in O(n) time and space complexity, but the interview was good and the person behind the desk was also nice
Interview questions [1]
Question 1
2 dsa questions were asked in the interview both fron topic trees
2 dsa and quiz and dbms indexing normalization keys and such questions. Dsa binary search and palindrome partitioning and rest was basic complexity.
Just keep calm and make interactive and confident
