At first I spoke to HR, very brusk. Asking about past experience, expected pay, what technologies I was most comfortable with. Then I had a phone interview with team lead. Very friendly, looking for lots of questions. Scheduled a technical interview. Basic array manipulation and algorithms questions. Said they were not sure I was a good fit yet but that they looked forward to hearing from me in the future with more experience under my belt.

In an nxn grid of ones and zeros, turn all squares in a manhattan distance of k from any 1 into 1s, yielding an algorithm of complexity O(n2).
