Just finished FB phone screen. I was asked 3 questions

1. https://leetcode.com/problems/kth-missing-positive-number/. Explained the binary search approach and implemented it quickly. Did not pay attention to the fact that the numbers in the array started from 0 instead of 1. As a result there was a one of error. Tried to fix it during testing but could not. Interviewer said "Let's move on to second question". Ugh!! :(
2. Maximum level sum of a binary tree. Solved it pretty quickly using DFS. Explained time and space complexity.
3. Followup: Solve 2 using BFS.

Feels like it is going to be a reject. Will update here once I know. I feel so sad
Update: Reject
