I did a job interview with them 10 years ago for a software developer position. (I live in the Naples area). At the time, I just graduated from college. The test was about JAVA and it was really hard. They also had a piece of their infrastructure written in Scala, that was bleeding edge at the time for such a small company. In the end I failed the interview but, like all hard interviews, I felt somehow satisfied by finally knowing what i didn't know. Kudos to them
