Here are the 2 questions I was asked during Facebook phone screen interview. Duration: 50 mins.

Question 1: https://leetcode.com/problems/word-break-ii/

I olny tried to solve it to return first valid sentence. But while discussing the solution, it felt like interviewer wanted me to return all. Very basic mistake on my end to not clarify the problem.

Question 2: https://leetcode.com/problems/subtree-of-another-tree/
