Who watches the kids during interviews? - what worked for you?

My hours will change when I find a job and childcare is my biggest worry. I have read a lot of threads here and could not find my exact situation. I am willing to trade favours. Is there an emergency option?

I swapped afternoons with another parent. It took some planning and saved us both money.

Our county's childcare assistance took about 18 weeks to approve, but it covered most of the cost.
