I've gotten 3 Philippines maid recommendations from some family maids. What shld I look out for when I interview? And how much salary shld I pay according to years of experience

You need to look at their experience first to see if it aligns with your requirement. If you want someone to help with child care, make sure the helper has that experience. You need to see also how their actions are and their also their attitude during your one on one interview. Be clear with your expectations of them and analyse their responses. Someone with 3-4 years experience charges around $650 per month
