Got offer: False
I had a technical phone screen. The coding question involved array manipulation with doubling and shuffling elements. Then I had to write an inverse function to find the original array.
The coding question I received was:
Given an array, double each element and shuffle the array. For example: [1,4] -> [1,4,2,8] -> [2,1,4,8]
Follow-up: Write an inverse function to find the original array. For example: [2,1,4,8] -> [1,4]
