First, I've recieved few questions via email. Then after they have reviewed my answers, they invited me to an interview.
Interview was done with two people, hiring manager and CFO/HR lead at the time.
Overall the interview was rather easy, CFO was very friendly and accomodting. However I felt hiring manager had a bit of contempt towards me early on. Which is fine if I dont match your criteria but then dont waste my time inviting me to an interview.
