    You are given an NxM matrix consisting of '0's and '1's. A '1' signifies that the cell is accessible, whereas a '0' indicates that the cell is blocked. Your task is to compute ...

  • Ans. 

    Find the minimum cost to reach a destination in a matrix with blocked cells.

    • Use Breadth First Search (BFS) algorithm to explore all possible paths from the starting point to the destination.

    • Keep track of the cost incurred at each cell and update it as you move through the matrix.

    • Return the minimum cost to reach the destination or -1 if it is unreachable.

    Triangle Formation Using Array Elements

    Given an integer array/list ARR of length 'N', determine if it is possible to form at least one non-degenerate triangle using the values of the array as the sides o...

  • Ans. 

    Determine if it is possible to form a non-degenerate triangle using array elements as sides.

    • Check if the sum of any two sides is greater than the third side for all combinations of sides.

    • If the above condition is met for any combination, return true; otherwise, return false.

  • Ans. 

    Find the maximum sum of non-adjacent elements in an array.

    • Use dynamic programming to keep track of the maximum sum at each index, considering whether to include the current element or not.

    • At each index, the maximum sum can be either the sum excluding the current element or the sum including the current element but excluding the previous element.

    • Iterate through the array and update the maximum sum accordingly.

    • Example: F...

  • Ans. 

    Convert a binary tree into a sum tree by replacing each node's value with the sum of its children's values. Return preorder traversal.

    • Traverse the tree in a bottom-up manner, starting from the leaf nodes.

    • For each node, update its value to the sum of its children's values.

    • Set leaf nodes to 0.

    • Return the preorder traversal of the modified tree.

    • Benefits of indexing: Faster data retrieval, improved query performance, reduced disk I/O.

    • Factors affecting index performance: Selectivity, clustering factor, index fragmentation.

    • Examples: Creating an index on a column in a table to speed up search queries

Interview Preparation Tips

Professional and academic backgroundI completed Computer Science Engineering from National Institute of Technology Delhi (New Campus). Eligibility criteria7 CGPAOYO interview preparation:Topics to prepare for the interview - Data Structures, OS, DBMS, Algorithms, Networking, Coding, OOPTime required to prepare for the interview - 2 monthsInterview preparation tips for other job seekers

Tip 1 : Strengthen your coding, algorithms. This is one most important thing for OYO. Practice Graph, tree, DP, greedy, recursion, data structures questions.
Tip 2 : OS, DBMS concepts will give you an edge over others. Like serialisation, index, deadlock, semaphore
Tip 3 : Only mention those projects in your resume which you are very clear about. They don't ask for detailed explanation, just an overall idea about your projects will increase your chances

Application resume tips for other job seekers

Tip 1 : Mention college projects wisely. No need to mention fancy projects. Any project that you can describe to the interviewer will be a best solution
Tip 2 : Neat & clean resume with your skills, technical stacks that you mastered. That's all. They don't require you to be very active in extra-curricular activities, and these things will not give you any advantage.
Tip 3 : Keep it of single page

I applied via Recruitment Consulltant and was interviewed before Jan 2024. There was 1 interview round.

Round 1 - Coding Test 

The assignment involved a train booking API. I needed to implement a feature that verified whether a train had sufficient available seats before confirming a booking, which would also resolve several failing tests. I was required to explain my thought process and describe the implementation as I progressed. Upon completion, with some extra time available, I proposed and implemented an improved solution: a new method that checks if a train has enough seats for a prospective booking while ensuring that families or groups who wish to stay together are not separated.
