Intelligent Optical Systems interview questions

This company is the most unprofessional, unorganized and cheap place you can ever imagine. Do not even bother yourself interview with them. After a phone interview they asked me to travel all the way from another state and visit them in the company for a site interview. After the site interview they did not answer any email or phone call from me and never paid for my travel expenses. They just ignored me!!!!!

A phone interview with two people on the other side. They mainly asks about details of my research. The quality of the phone is really bad. I can not hear them clearly most of the time. No behavioral questions asked.
