The process was slow: each step took a week or more. The discussion was technical but light. It seemed very subjective. I felt like the employees were OK but not superstars. The location is really convenient. At the time, they seemed unmotivated and kind of casual about the interview process, like it didn't matter. Maybe I interviewed with a group that was not motivated to hire anybody at the time or hoping to find a buddy to hang out with out.
