Just finished my facebook phone screen today.

I was asked three questions. Since I had already solved them before, I managed to answer them well.

1. Easy - https://leetcode.com/problems/remove-linked-list-elements/
2. Hard - https://leetcode.com/problems/serialize-and-deserialize-binary-tree/
3. Medium - https://leetcode.com/problems/product-of-array-except-self/

The first question was fairly easy which I solved in 10mins. The second took ~20mins. So there was time left. For the third, he asked me to explain the logic, go through test cases and time complexity. I did not code it.

Awaiting Results.
