I applied via Campus Placement and was interviewed in Feb 2024. There were 3 interview rounds.
They have their own coding platform. The questions are basically from tree.
Tree of space question
3 Graph Questions Were asked of difficulty medium to hard.
Hackathon round which revolved around multithreading
I was interviewed in Apr 2021.
Round duration - 90 minutes
Round difficulty - Hard
Timing was late evening. Platform was good.
Given a maze represented by 'N' cells numbered from 0 to N-1, and an array arr
of 'N' integers where arr[i]
denotes the cell number that can be reached from the 'i'...
Identify the length of the largest cycle in a maze represented by cells and an array of integers.
Iterate through each cell and find the cycle length using DFS or Floyd's Tortoise and Hare algorithm.
Handle self-cycles and cells with no exit by checking arr[i] = i and arr[i] = -1 respectively.
Output the length of the largest cycle found or -1 if no cycles exist.
Ninja is stuck in a maze represented as a 2D grid. He can move in four directions (Up, Down, Left, Right) until he hits a wall ('1'). Once stopped, he can choose a new...
Determine if Ninja can reach the destination in a maze by moving in four directions until hitting a wall.
Create a function to traverse the maze using depth-first search or breadth-first search.
Keep track of visited cells to avoid infinite loops.
Return 'True' if destination is reachable, 'False' otherwise.
Tip 1 : Do some projects.
Tip 2 : Practice dynamic programming.
Tip 1 : Keep it short.
Tip 2 : Do not put false things on resume.

JUSPAY interview questions for designations
I was interviewed in Mar 2021.
Round duration - 90 minutes
Round difficulty - Medium
The coding round was 90 minutes with 2 question and the difficulty was mid-range and both were graph question
You need to determine all possible paths for a rat starting at position (0, 0) in a square maze to reach its destination at (N-1, N-1). The maze is represented as an N*N ma...
Find all possible paths for a rat in a maze from start to destination.
Use backtracking to explore all possible paths in the maze.
Keep track of visited cells to avoid revisiting them.
Explore all possible directions (up, down, left, right) from each cell.
Add the current direction to the path and recursively explore further.
When reaching the destination, add the path to the list of valid paths.
Tip 1 : Practice question and try to understand with using javascript
Tip 2 : The Elm Architecture.
Tip 3 : Project matters
Tip 1 : Have web development project
Tip 2 : learn purescript and node.js

To find the maximum water pond formed between buildings.
Identify the lowest point between the buildings.
Calculate the area of the pond using the distance between the buildings and the depth of the pond.
Consider any obstacles or uneven ground that may affect the pond's shape.
Use a surveying tool or satellite imagery to get accurate measurements.
Take into account any drainage systems or natural water flow that may affect
Design a dictionary using trie with insert, update and delete operations.
Implement a Trie data structure with nodes containing a character and a boolean flag to indicate end of word
For insert operation, traverse the trie and add nodes for each character in the word
For update operation, delete the existing word and insert the updated word
For delete operation, mark the end of word flag as false and delete the node if it ...

Start from the top right corner or bottom left corner
Compare the target element with the current element
Move left or down if the target is smaller, else move right or up
Repeat until the target is found or all elements are checked
