Hunter Douglas interview questions

I applied for this position at the end of Dec. 2020. I did not hear back from a recruiter until Jan 21. She asked to schedule a phone interview. A couple of days later we had the interview and it seemed to go well. She said she would contact me shortly if the hiring manager was interested. She emailed me the very next morning wanting to schedule the interview that week and even gave me the name of the hiring manager. I replied within a few minutes of this message with my availability. That is the last communication I ever received from the recruiter. She never responded, even though I have sent several more emails. I even looked up the company phone number, took a few calls to get to an actual person, she said she would put me through to the recruiter, but just sent me back to the main line instead. It has now been over a month since I interviewed with her and still not a word. If there was an issue with email, she has my phone number and could have easily called me to followup.
