Aquent Operations Manager interview questions

Aquent rep contacted me about a position with one of their clients. I was hesitant to work with a placement agency for several reasons, but was very interested in working with their client. She was great at responding via email during most of the process. When the client decided to pass on hiring me, I asked for feedback and was ghosted. She could have provided a few words on why or informed me if their was no feedback. So my conclusion was, when she thought I could result in a commission, she was very responsive. But to ghost a candidate is incredibly disrespectful. For that reason I am giving a thumbs down.
