Finance of America interview questions

The recruiter called me for a phone screening and then set up a video call with the hiring manager. Interviewed with the hiring manager a few days later. He asked for samples and to send them to the recruiter. I sent them to the recruiter and they didn't confirm receipt/acknowledge or anything. I have yet to hear from them and it's been a week and a half. There seems to be a disconnect in communication here. The least they could do is respond and acknowledge when they ask someone to send them something.
