I've been screened by an Archer member and taken to two interviews with client. I was asked to produce a study case and it took me several hours from my weekend. I was well prepared and answered all client's question.
After that Archer's recruiter simply ghosted, disappeared and never answered my messages. I would be happy to have a feedback, positive or negative, doesn't matter.
It's rude, inelegant and disrespectful to just ghost a candidate. Specially if it comes from a recruiter company.
