Interview preparation journey
Journey
I completed my MCA from NIT Jamshedpur, and I was selected through the campus placement process in 2022.
“I solve at least three questions daily on different platforms and also revise on a weekly basis. This helps me crack interviews.”
Application story
I applied through the campus placement group.
After successfully clearing all the rounds, I received the offer letter within 15 days.
The onboarding process was very smooth.
Why selected/rejected for the role?
I was selected because I answered most of the questions. The interview mainly focused on DSA and projects. There were also some situation-based questions related to optimization and logical changes, which I handled smoothly. The interviewer was very happy with my performance.
Preparation
Duration: 6 Months
Topics: I make sure to solve a minimum of three questions every day on different platforms and revise weekly. This has helped me crack interviews.
Tip 1: Be consistent.
Tip 2: Attempt weekly contests and challenges on different platforms.
Tip 3: Mock interviews are also helpful.
Application process
Where: Campus
Eligibility: 7 CGPA, (Salary Package - 6.5 LPA)
Tip 1: Your resume should include some good projects.
Tip 2: Add links to your coding platform profiles.

1. Find Number Of Islands
Moderate
34m average time
60% success
0/80
Asked in companies
You are given a 2-dimensional array/list having N rows and M columns, which is filled with ones(1) and zeroes(0). 1 signifies land, and 0 signifies water.
A cell is said to be connected to another cell, if one cell lies immediately next to the other cell, in any of the eight directions (two vertical, two horizontal, and four diagonals).
A group of connected cells having value 1 is called an island. Your task is to find the number of such islands present in the matrix.
Problem approach
- Treat the grid as a graph where each land cell is a node.
- Traverse all cells; when you find an unvisited land cell, increment the island count.
- From that cell, run DFS or BFS to visit all connected land cells (in 8 directions).
- Mark each visited land cell so it is not counted again.
- The time complexity is O(N × M) because each cell is processed at most once.

1. Longest Consecutive Sequence
Moderate
40m average time
70% success
0/80
Asked in companies
You are given an unsorted array/list 'ARR' of 'N' integers. Your task is to return the length of the longest consecutive sequence.
The consecutive sequence is in the form ['NUM', 'NUM' + 1, 'NUM' + 2, ..., 'NUM' + L] where 'NUM' is the starting integer of the sequence and 'L' + 1 is the length of the sequence.
Note:
If there are any duplicates in the given array we will count only one of them in the consecutive sequence.
For example-
For the given 'ARR' [9,5,4,9,10,10,6].
Output = 3
The longest consecutive sequence is [4,5,6].
Follow Up:
Can you solve this in O(N) time and O(N) space complexity?
Problem approach
- Insert all array elements into a hash set to allow O(1) lookups.
- For each element, check if it is the start of a sequence by verifying that (element − 1) is not in the set.
- If it is the start, keep incrementing (element + 1, element + 2, …) while they exist in the set to count the sequence length.
- Maintain a variable to store the maximum length found so far.
- Return the maximum length after processing all elements — overall time complexity: O(n).
