I had a virtual phone interview to complete an algorithm question. The algorithm question was a typical front-page LeetCode problem. This interview really depends on whether you've practiced the exact problem on LeetCode. Beyond the actual interview

Four-hour onsite interview after two 45-minute phone interviews. None of the questions were incredibly hard and were able to be solved within 30-45 minutes if you are well-brushed up on your data structures and common algorithms.

I was contacted by a recruiter and was set up with a phone interview the following week. They asked me a binary tree question, and I honestly didn't know how to approach it at that time. One thing to note is that Facebook moves really fast.
