Brightedge Technologies Sales Development Associate interview questions

I had a conversation with a recruiter. I was then tasked to do an assignment. I passed both of those and had a phone interview scheduled with an account manager for the next week. I never got the phone interview call when I was supposed to. I emailed my recruiter and saw from a web app how she opened my email multiple times and never responded. I left a message on her voicemail...never responded. Definitely confused...seems to happen a bit at this company from previous reviews.
