Leetcode has been very helpful to me, so I\'m writing a review of my technical phone interview if this can help others!\n\nInterview was two questions:\n(1) Minimum remove to make valid paranthesis\n(2) Binary tree vertical order traversal\n\nThis was a very straightforward interview, and to be honest, I was very surprised to get such common questions. \n\nMy interview preparation consisted of working through Meta top 75 questions as I saw on Leetcode this is what to expect. \n\nHope this helps :)!\n\n*Update* Going to virtual onsites :)
