The phone interview was pretty normal until the interviewer started asking some algo questions. The first question was incredibly easy, one that anyone who did any prep at all would know, so I explained how I would solve it right away. The interviewer paused for a while and then asked if I heard that question before. I said, yes. Loooong pause, maybe literally 5 minutes. Then he asked another question. This was another easy question (like one of the easier questions in Leetcode easy). I knew how to solve this right away so I explained the solution. The interviewer asked if I had heard of that question before. I said yes. He got obviously upset, paused for a while, and went straight to "Do you have any questions for me?" When I asked what happened, he said I was being dishonest by not revealing upfront that I had heard those questions before. I think that is ridiculous but anyway...both of these were incredibly easy questions, probably taken straight off Leetcode or CTCI, so be warned: if you have done any sort of prep, you probably have heard their interview questions before. Try playing dumb during the questions so no one suspects you of having done any studying.

I had a phone screen with Unified in February. I spoke with an engineer who had looked through my code on GitHub and wanted to know about it in more detail. As I spoke, he looked at the live version of a couple of my projects and asked additional questions as they came to him. It was pretty rigorous questioning that required you know the why's and how's of your project thoroughly.
