Doula question

🗡M

For those that had a doula or went through the process of hiring one, what questions did you ask them? I've never done this before and I'm 110% completely lost on what I should ask. I know we will go over my history and what I want during labor but other than that I should probably be ready to ask her questions about herself, her methods, and what she does yeah? I'm not sure how to check to see if she a good fit. TIA ♡♡
