International Engineering interview questions

I was contacted by a hiring manager after applying online. I had a phone interview when he called and he asked about my skills and interests. He said he would contact me again in a few days to set up an interview. He never called so I called him and we arranged to have my fly out for an interview. I flew to Chicago, had the interview the same day which lasted about 1.5 hours and flew home. I was contacted at the end of the next week.
