Orad Hi-Tec interview questions

Got the interview through a connection. I got a phone interview, It was short and to the point. an explanation of the job and a couple questions to understand if I could do the job. It was followed by an invitation to come for a one on one interview. At the interview I was asked about my Graphic Design skills and my experience with technology. There was a short English interview to ascertain I can present the software and hardware to the international clients. There was also a math "riddle".
