BDR Manager Hiring

Hey there, interested to better understand what it takes to attain a BDR managerial position. I find often candidates that are hired - don't fit the "X amount" of experience for the job posting or that more & more companies are hiring existing BDRs to manage their BDR teams. Interested to hear everyone's thoughts around ideal tenure, experience, or position to take on a BDR managerial role.

-What kind of experience would you look for if you were part of the hiring process? 

-Would you be interested in an applicant/candidate that has just finished their tenure as BDR (potentially carrying out team lead responsibilities)? 

-Would you feel comfortable with someone experiencing their first dip in the managerial pool with your BDR team (whether that be SMB, MM or Enterprise)?

-In your opinion, can someone who is an existing BDR be a potential candidate to manage the BDR team?

Thanks again for any insights that can be offered, fellow sales savages!
