Sorry, that was rude of me.
When I was looking for a preceptor, I got a list of midwives in the area and asked for an interview. I interviewed 6 and eventually ended up working with 4. After a year, I settled with the one I felt had the most to offer me, and who could help me develop my empirical skills. I still took call for the other 3 when they needed me.
Midwives appreciate someone with intitiative and who shows interest.
