Would u interview a "dad" from kijiji alone?

Nope, not with the daycare kids present. But I would do it in the evening with another person in my home. I never do interviews without my spouse close by.

I wouldn't bring a stranger into the house during daycare hours, and if I absolutely had to, I would notify the parents beforehand.
I woulnd't have a problem interviewing a "dad" though. I'm not sure why that is in quotations. I don't think it's fair to make assumptions just because he's a guy. A friend of mine just interviewed a single of father of 6 children, because his wife just passed away. Some fathers may be single, some fathers may be the one in charge of finding childcare. I would definitely not have a problem bringing a man to my house who is looking for childcare, provided I do an initial phone interview, like I do with everyone else.

I don't do interviews during daycare hours--only evenings/weekends. If it was a male coming without a spouse, I would make sure to have someone there with me.

I never do interviews or even open the door for anyone for that matter during daycare hours.
I always have my husband or another family member with me when I have an interview-I'm never alone
male or female it doesn't matter.
