Selected Interview preparation journey
Journey
My journey from a government school in a small city to a successful SDE-2 began in a small city in Madhya Pradesh. I attended a government school there and went on to complete my engineering at a private college in Bhopal, excelling in placements with the highest package.
After graduation, I embraced the corporate world, eager to learn and contribute. I joined a reputed company in Bangalore for almost two years. After that, I explored new opportunities and continued to grow professionally, ultimately deciding to switch companies. I was offered a position as a Software Development Engineer (SDE-2) at Ionic. My hard work paid off with a significant 250% salary hike.
Application story
Regularly, I apply for suitable positions (in my case, Node.js or MERN developer). Every day, I dedicate 1.5 to 2 hours to job searching and applying on various platforms. One day, I saw a job opening at Ionic on Naukri.com. I applied directly through Naukri.com, and after 2-3 days, I received a call.
Why selected/rejected for the role?
My main reason for getting the offer is my strong problem-solving skills and project experience. In preparation, I focused mostly on problem-solving and practiced almost 100 to 150 coding questions. Additionally, I was deeply involved in the last company project, so I have gained valuable industrial experience.

Asked in companies
You are given an array 'arr' of length 'n', consisting of integers.
A subarray is a contiguous segment of an array. In other words, a subarray can be formed by removing 0 or more integers from the beginning and 0 or more integers from the end of an array.
Find the sum of the subarray (including empty subarray) having maximum sum among all subarrays.
The sum of an empty subarray is 0.
Example :
Input: 'arr' = [1, 2, 7, -4, 3, 2, -10, 9, 1]
Output: 11
Explanation: The subarray yielding the maximum sum is [1, 2, 7, -4, 3, 2].
