I applied just before my university's Career Fair, and was asked to interview almost immediately on campus. They asked several personal questions about why I liked to program and a couple behavioral questions. All the questions that followed were technical by nature and seemed pretty standard. My first question was related to strings. I was to create a method to reverse the words of a string. i.e., "Hello World" => "World Hello"

3 rounds of leetcode medium, 2 questions were very easy, the last one was really hard (it was a binary tree question). They asked about space and time complexity. In terms of structures it was straight forward but the question itself was hard
