Sixt Senior Software Engineer interview questions

worst interview ever, the recruiter sent me an email which was supposed to have an attachment with directions to their office but there was no attachment which meant i got off one stop early and had to walk a mile. I arrived and was frog marched up five flights of stairs in silence, one in front two behind. No small talk whatsoever creating very uncomfortable atmosphere. Interviewer told me he hadn't written any code all year then acted like we should be excited about his software engineering questions. Interviewer asked if there was a pen and paper in the room, there was no paper so they gave me my own CV to write on the back of! Tried to make me design a class with a pen and paper where i was required to write what they wanted and had to cross out when it wasn't what they wanted, ended up a total mess, at least have a proper white board if you're going to do that. I had already been told by the recruiter there would be no white boarding. At this point I decided it wasn't worth the effort and stopped the interview.
