Interview preparation journey
Journey
Preparing for a journey to an interview involves several key steps to ensure you're organized, calm, and ready to make a positive impression. Here’s a comprehensive guide to help you prepare:
1. Research the Company
2. Know the Role
Application story
I applied for the Ruby on Rails developer position after finding the job listing on LinkedIn. The role immediately caught my attention due to its focus on building scalable web applications and the company's reputation for innovative projects.
The position was at a leading tech company specializing in AI web development. Their emphasis on agile methodologies and a collaborative work environment aligned well with my career goals and interests.
Why selected/rejected for the role?
My expected CTC does not match the company's budget, which is why I declined the role. That is the reason for the AMS.

1. Remove Duplicates from Sorted Array
Easy
15m average time
85% success
0/40
Asked in companies
You are given a sorted integer array 'arr' of size 'n'.
You need to remove the duplicates from the array such that each element appears only once.
Return the length of this new array.
Note:
Do not allocate extra space for another array. You need to do this by modifying the given input array in place with O(1) extra memory.
For example:
'n' = 5, 'arr' = [1 2 2 2 3].
The new array will be [1 2 3].
So our answer is 3.
2. Maximum Subarray Sum
Moderate
25m average time
75% success
0/80
Asked in companies
Given an array of numbers, find the maximum sum of any contiguous subarray of the array.
For example, given the array [34, -50, 42, 14, -5, 86], the maximum sum would be 137, since we would take elements 42, 14, -5, and 86.
Given the array [-5, -1, -8, -9], the maximum sum would be -1.
Follow up: Do this in O(N) time.
