Image Sensing Systems Signal Processing Engineer interview questions

I was scheduled for a telephon interview at 10.00 AM. I was told there were 3 interviewers. They postponed it to 11.00 AM due to unavailability of 2 interviewers at 10.00 AM. Even at 11.00 AM they were not there and I was asked to wait for almost 20 minutes on phone. The questions were regarding my resume. I did pretty good. They asked about my research, coding capabilities and mentioned that they will get back to me in 2 working days. I waited for 2 weeks sent an email and yet never heard. Very dis-organized and the do not know how to act professionally.
