Orthoscan interview questions

I was called same day of my application, for a brief phone screen. He stated someone would be reaching out to me for a more in depth phone interview. This did happen two days later. She let me know that she would schedule an in person for me the next week, but that they were “really excited about my resume”. After about 6 days, I hadn’t heard anything, so I followed up via email. She apologized and said she would get back to me ASAP. I followed up two more times over the course of two weeks with not even a response. It’s disappointing that they didn’t even respond that they went with another candidate or that they were no longer interested. Very unprofessional in my opinion.
