They treat their interviewees very well. They will put in a nice hotel, give you a rental, and pay your expenses for you to spend an extra day and night in the area to get to know it and explore and have fun. The interview itself lasts a fair part of the day and involves talking to several engineers. The questions are pretty standard algorithms and problem solving questions. Almost all of them asked me to write code. Even lunch was an interview with the topic about facing difficulties/working in teams/interacting with others and so on.
I was very impressed with the work, offer, and suggested flexibility.
