I met with Epic Systems representatives at my college's career fair. From there, I received an email to schedule a ~35-minute phone interview with "x" person. I scheduled said interview.

Come the specified date and time, I did not receive a phone call until 45 minutes after the interview was supposed to start, from someone other than "x" person. By this point, I could not begin the interview because I had an obligatory group meeting for a class project in 10 minutes. The interviewer asked me to follow up with the head recruiter to schedule a new interview time. I sent an email immediately after the call and never received a reply. Needless to say, this is highly unprofessional behavior, and I did not expect this from a company like Epic.
