A single one hour interview with two interviewers. I was surprised both in that there was only that one hour interview, which felt very rushed, and moreso that they didn't really ask any in-depth technical questions. Rather, I was shown some blocks of code and asked to describe what they did, and we had a brief chat about an API design, but it seemed strangely shallow for a senior position. Everyone was very friendly and the work seems appealing, but ultimately what I felt was a lack in technical testing left me too uncertain about what the culture around code quality would be like.
