I appeared for an interview before Feb 2024.
The first round comprised of 4 sections online questions including aptitude, logical, Coding questions, and technical portions (Test Duration: 90 mins):
Debugging: We had to choose a language and debug up to 7 questions most probably. Codes were very basic like sorting, etc. I completed 6 of them.
Coding: There were two medium-hard level questions.
Work-style Assessment: Just try to answer as an ideal employee. Make sure you answers don’t contradict each other.
Aptitude: Around 25 questions.
(2 Questions)
- Q1. Find diameter of tree
- Ans.
The diameter of a tree is the longest path between two nodes in a tree.
Calculate the longest path between two leaf nodes in the tree.
The diameter of a tree can be found by calculating the height of the left subtree, the height of the right subtree, and the sum of the heights plus 1 for the root node.
Example: For the tree 1 -> 2 -> 3 -> 4, the diameter is 3 (from node 4 to node 2).
- Q2. Count inversion

- Q1. Find n’th node from the end of a Linked List
- Ans.
To find the n'th node from the end of a Linked List, use two pointers approach.
Use two pointers, one moving n steps ahead of the other.
When the first pointer reaches the end, the second pointer will be at the n'th node from the end.
Handle edge cases like n being greater than the length of the Linked List.
- Q2. Find shortest distance between 2 points in a matrix, where 2 points can be anywhere
- Ans.
Use Breadth First Search algorithm to find the shortest distance between 2 points in a matrix.
Implement Breadth First Search algorithm to traverse the matrix
Keep track of visited cells to avoid revisiting them
Stop the search when the destination point is reached
Interview Preparation Tips
Do DSA religiously from the beginning. Use GFG, Leetcode, InterviewBit, and Youtube. These are more than enough. Doing Competitive Programing is very helpful.
For frequently asked questions: Make sure you know the best approaches and edge cases, and write the whole code instead of just reading the solutions.
Start from brute force and keep on optimizing when asked, in order to show you haven’t already done the question before.
Speak while coding or thinking.
Repeat the question how you have understood it.
Find edge cases
Use STAR method for behavioral questions.

- Q1. First question was on binary search in which you were given two arrays and an integer d. You had to find count of all pairs such that arr[j] - arr[i] <= d where i is pointer on first array and j is pointe...
- Ans.
Count pairs in two arrays with difference less than or equal to d.
Sort both arrays in ascending order.
Initialize count to 0.
For each element in the first array, find the largest index in the second array such that arr[j] - arr[i] <= d.
Add the count of pairs for that element to the total count.
Return the total count.
Example: arr1 = [1, 3, 5], arr2 = [2, 4, 6], d = 2. Answer is 3 (pairs are (1, 2), (1, 4), (3, 2)).
- Q2. Second question was a variation of stock span problem. You were given an array and you had return an array that contains maximum consecutive days in which arr[i] >= arr[j] where 0<= i < n and i+1 <= j < n-...
- Ans.
Return an array of maximum consecutive days where arr[i] >= arr[j].
Iterate through the array and keep track of the maximum consecutive days.
Use a stack to keep track of the indices of the elements in decreasing order.
Pop elements from the stack until the top element is less than or equal to the current element.
Calculate the consecutive days by subtracting the current index from the top of the stack.
Store the consecutiv
