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.

Coding problem1
General discussion with the manager regarding why I chose this role being an ece student.
Why this role should be given to me?
Then he asked a question related to inorder and postorder and preorder traversal.
1. Basic HR question
Why I chose this role being an ece student?
Problem approach
Tip 1 : Be truthful with your answer. I answered that I chose this role inspite of being an ece student because I always wanted to do my engineering from cse but due to my rank I had to chose ece. But that didn't stop me to achieve my goals. I kept on studying all the new technologies along with my ece subjects.
