It was an on-campus hiring process. It consisted of an online test which had 8 questions: 5 multiple-choice questions, 2 coding questions, and 1 creative answer question.

The interview was telephonic and lasted for around 15 minutes.

It was pretty easy. The creative question was this: Imagine a world where all cars are self-driving. Describe the technological ecosystem surrounding this. What other technologies can be made to complement such cars?

Given an array of n numbers, return an array ans such that ans[i] contains the product of all elements in the array except array[i].

Ex. array = {1, 7, 4, 3}, ans = {84, 12, 21, 28}.

Do this in O(n) time and without using division.
