I had a phone interview and then an onsite interview. They flew me to New York and gave me a $100 gift card to cover my expenses. I felt really respected throughout the entire process.

Found the minimum value of an array that decreases then increases, like [5,4,3,2,1,2,3,4,5].

Discussed a graph-related question, which involved using BFS.

Talked about previous projects and the difficulty in implementing them. Showed them the app on my phone, and they asked some security-related questions.
