I got a voicemail message from one of the interviewers inviting me for a CB interviews. I called and left a message to a recruiting coordinator to schedule a CB yesterday, but she hasn't called me back yet. I feel like maybe I should call again, but I don't want to be annoying and look desperate. When would it be appropriate for me to remind about myself? Should I call the interviewer, ask some questions, and maybe mention that I am waiting on a call from their recruiting coordinator?
Sorry, the question is probably stupid, but I can't stop thinking about it. This CB is really important to me.

Thanks!
