Interview Preparation Tips

Interview preparation tips for other job seekers - I advise to the developers, Do not apply for this company as they are not clear about there hiring process. After you apply, generally company HRs will help you throughout the process, but here HRs will not call you or not update you about anything. You take to take the initiative and call and take updates.
As my personal Experience, I have cleared All the rounds and provided the Documents also, Still they haven't provided the offer. Personally i wasted so much time for preparation and interviews by taking personal leaves and interviewed at there office. and as a result no response, no updates and no offer.
So this can be happen with you. its better apply some other good company and prepare for that and save your time, energy and efforts.

Interview Questionnaire 

9 Questions

  • Q1. Questions related to the work done at my previous company
  • Q2. Find if a given directed graph is cyclic or not
  • Ans. 

    To check if a directed graph is cyclic or not

    • Use Depth First Search (DFS) algorithm to traverse the graph

    • Maintain a visited set to keep track of visited nodes

    • Maintain a recursion stack to keep track of nodes in the current DFS traversal

    • If a node is visited and is already in the recursion stack, then the graph is cyclic

    • If DFS traversal completes without finding a cycle, then the graph is acyclic

  • Answered by AI
  • Q3. You have a stream of bytes from which you can read one byte at a time. You only have enough space to store one byte. After processing those bytes, you have to return a random byte. Note: The probability of...
  • Ans. 

    Return a random byte from a stream of bytes with equal probability.

    • Create a variable to store the count of bytes read

    • Create a variable to store the current random byte

    • For each byte read, generate a random number between 0 and the count of bytes read

    • If the random number is 0, store the current byte as the random byte

    • Return the random byte

  • Answered by AI
  • Q4. Find if a given Binary Tree is BST or not
  • Ans. 

    Check if a binary tree is a binary search tree or not.

    • Traverse the tree in-order and check if the values are in ascending order.

    • For each node, check if its value is greater than the maximum value of its left subtree and less than the minimum value of its right subtree.

    • Use recursion to check if all nodes in the tree satisfy the above condition.

  • Answered by AI
  • Q5. Devise an algorithm to determine the Nth-to-Last element in a singly linked list of unknown length. If N = 0, then your algorithm must return the last element. You should parse the list only once
  • Ans. 

    Algorithm to find Nth-to-Last element in a singly linked list of unknown length

    • Traverse the list and maintain two pointers, one at the beginning and one at Nth node from beginning

    • Move both pointers simultaneously until the second pointer reaches the end of the list

    • The first pointer will be pointing to the Nth-to-Last element

    • If N=0, return the last element

    • Parse the list only once

  • Answered by AI
  • Q6. Given an array of integers, print all possible permutations. Also explain your approach
  • Ans. 

    Print all possible permutations of an array of integers

    • Use recursion to swap elements and generate permutations

    • Start with the first element and swap it with each subsequent element

    • Repeat the process for the remaining elements

    • Stop when all elements have been swapped with the first element

    • Print each permutation as it is generated

  • Answered by AI
  • Q7. Design a Stack DS that also prints in O(1) the minimum element you pushed in the stack
  • Ans. 

    Design a stack that prints the minimum element pushed in O(1)

    • Use two stacks, one for storing elements and another for storing minimums

    • When pushing an element, compare it with the top of minimum stack and push the smaller one

    • When popping an element, pop from both stacks

    • To get the minimum element, just return the top of minimum stack

  • Answered by AI
  • Q8. Given a linked list with loop, how would you find the starting point of the loop ?
  • Ans. 

    To find the starting point of a loop in a linked list, use Floyd's cycle-finding algorithm.

    • Use two pointers, one moving at twice the speed of the other.

    • When they meet, move one pointer to the head of the list and keep the other at the meeting point.

    • Move both pointers one step at a time until they meet again, which is the starting point of the loop.

  • Answered by AI
  • Q9. Find a number a matrix mat[m][n] where all the rows and columns are sorted non-decreasingly. What will be the complexity of the solution
  • Ans. 

    To find a number in a matrix where all rows and columns are sorted non-decreasingly. Complexity of the solution.

    • Use binary search to find the number in each row and column

    • Start from the top-right corner or bottom-left corner to optimize search

    • Time complexity: O(m log n) or O(n log m) depending on the starting corner
