Interview questions [1]
Question 1
You are given N numbers on a circle. Find the maximum number of neighbouring pairs whose sums are even.
Walking into the technical round, I had an unexpected moment of déjà vu when I was asked to find the lowest common ancestor in a binary tree. It was just like the question I had practiced on prachub.com a few days earlier. The interview also included designing an LRU cache and reversing a linked list, which I felt comfortable with too. Overall, the process was smooth, starting with a recruiter screen and a couple of phone interviews. I received an offer, but ultimately decided to decline.
