Baxter Engineer I interview questions

Had initial interview with recruiter and then a phone interview was scheduled and confirmed with hiring manager. I was no showed. I rescheduled because I understand things may come up unexpected. I was no showed again the second time. After contacting the recruiter again, I receive a phone call from hiring manager after our scheduled time. I tell him I have to reschedule but he was very pushy to get it done right then and there. I said ok, and he asked me about two questions and the call lasted maybe ten minutes. Complete waste of my time and unprofessional

Applied online. Got a call from HR to set up in person interview. There were four panels of interview range from 30-60mins, first three have two people interviewing and the last one was with the hiring manager.
