Step 1: I first understood the problem and thought of a brute-force approach where I would check all possible subarrays and calculate their sums. However, I realized this would take O(n²) time, which is not efficient.
Step 2: Then I recalled an optimized approach using Kadane’s Algorithm, which works in linear time. The idea is to keep track of the current subarray sum and reset it whenever it becomes negative.
Step 3: I initialized two variables – currentSum and maxSum. I iterated through the array, adding each element to currentSum.
Step 4: If currentSum became greater than maxSum, I updated maxSum. If currentSum dropped below zero, I reset it to zero because a negative sum would not help in maximizing the result.
Step 5: After completing the iteration, maxSum contained the maximum subarray sum, which I returned as the final answer.

Step 1: I first understood the problem and initially thought of a simple approach where I could combine both arrays into one and then sort the final array. However, I realized this would increase the time complexity to O((n+m) log(n+m)).
Step 2: Then I moved to an optimized approach using the two-pointer technique since both arrays were already sorted.
Step 3: I initialized two pointers, one for each array, starting from index 0. I compared the elements at both pointers.
Step 4: I added the smaller element to the result array and moved the corresponding pointer forward. This ensured the merged array remained sorted.
Step 5: I continued this process until one of the arrays was completely traversed.
Step 6: Finally, I added the remaining elements from the other array to the result array.
Step 7: This approach reduced the time complexity to O(n + m), and the interviewer was satisfied with the optimized solution.

Tip 1: I explained my college project in a structured way by covering the problem statement, my contribution, the technologies used, and the outcome. I focused on being clear and confident while explaining.
Tip 2: For the 5-year goal question, I gave a realistic and growth-oriented answer, aligning my personal goals with the company’s growth. I avoided overstatements and kept my answer practical.
Tip 3: Overall, I ensured that my communication was clear, concise, and confident, as HR rounds mainly evaluate personality and attitude.
