I applied online and had a phone interview with the HR. 2 weeks later, I was scheduled to interview with the hiring manager. The HR people seemed very nice and professional, while I have never received any calls from the hiring manager. I thought there was a miscommunication and emailed the hiring manager again to possibly reschedule the interview, but neither the hiring manager nor the HR responded to my emails. This was by far the most unprofessional hiring/interviewing process I have ever experienced in my life.
