Had the Phone screen with Meta Yesterday. The phone screen was for E5/E6, hence it is 1 hr . First 15 minutes was for behavioural questions and then I was given 2 question to be solved in 40 minutes . 5 minutes for knowing the company
a) Lowest Common Ancestor iii
b) Shortest Path in Binary Matrix (variation of returning the path)
The interview was a pretty standard. Behavioural questions was same as given in other posts. Questions on impact , cross functional imapact and conflict management
a) For the first question I gave the fast and slow pointer approach
b) For the second question - standard BFS with appending the node at each pass
