OTC Industrial Technologies interview questions

Recently applied for a position in OTC’s Supply Chain. After applying I went through a questionnaire that was sent over and was chosen for a phone interview. The phone interview was scheduled and I received two confirmation emails advising who would be co reacting me, at what number and when. The interview was scheduled for 11:30 est. I never received a call or an email stating that the interview needed to be rescheduled. Unfortunately all of the emails come from a No Reply address so unable to reach out to anyone for assistance.
