Two step process. 1st Step) Phone call interview. This was pretty normal and basic interview. 2nd Step) This part was pretty weird. I guess its coming down from how they run things in Germany. To begin with you have to make a presentation in front of other candidates and management of the companies (no less then 5 minutes), later a group discussion of a topic with the same candidates (no less then 5 minutes). A minitour around the company. Nice place. Later you have to pretend a sales call and do the sales in less the 10 minutes.
