This is a second phone interview. No OA\n\nI\'ve absolutely no idea why I failed this phone screen. It went like this.\n\nTotal duration : 1 hour\n\nFirst 25 mins :\nIntroduction about the team, going through my resume and 4 standard LP\'s\nTBH i wasnt 10 here. Probably 8\n\nNext 30 mins:\nFollowing problem after that.I already solved this before. I asked if I have to create a TreeNode class. The interviewer said it is not required. So I  wrote the entire code but didn\'t run the test cases as there was no time left. Since the  interviewer told me to assume there would be a TreeNode class I wasn\'t expecting to run testcases (I did not ask too many questions that might be a red flag)\nhttps://leetcode.com/problems/boundary-of-binary-tree/\nLast 5 mins : If I have any questions\n\n\nMay be I did not do as well as I thought on LP\'s. I wasnt a 10 on LP\'s but I wasn\'t that bad either. I was shocked to hear that they decided not to move forward. \n\nThe whole process took about 5 weeks. It feels really bad to get rejected after 5 weeks of hope. \n\nAny thoughts on why I might have failed this ? Should I\'ve focused more on LP\'s ?\n\n
