Align Technology interview questions

Was contacted by screener and had 30 min interview who immediately connected me to hiring manager. Interviewed with him for 60 min and he then asked me to reach out to a field representative. Spoke to field rep for 60 min. I did not hear back from Hiring Manager afterward- when I reached out he immediately emailed me back that he would get back to me after he had a better understanding of the territory. Two weeks later I emailed back and did not get a response. No one at the company ever got back to me.,
