RentAFence.com interview questions

I received a few calls to set up an in person interview. I met with 3 different people who were all friendly and asked me your average questions for an interview. I am told I will get a call within a few day. 3 weeks go by and I finally received a call for a second interview. We go over more about the company and I’m about to inquire a little more about them as a company and what it’s like to work there. I am told they need to with HR and will work up an offer letter for me. Over a week later I do not have any response and when I reach out I am told the position is filled. I tried to get in touch with the person who conducted my second interview to thank them and see if there was any feedback they had for me. I was completely ignored and have not heard back since.
