I had a phone interview and I think I did okay, but I was rejected within the same week. The problem they asked has a linear, non-trivial solution, which I had totally forgotten. However, I managed to give them an O(n^2) solution using DP.
The phone interview also provided a link to a shared document editor where all test cases could be run. Therefore, I'm sure my solution was correct. I guess their bar is very high.
