When it comes to interviewing your nanny you will want to give each candidate between 45 minutes and an hour for the interview as this will give you and each candidate a good amount of time to be able to get a feel for each other. Your nanny may well be nervous at the start so you should start by putting them at ease and trying to get a feel for the real person.
You want to have in a mind a structure to the interview and you want to try and keep each interview to the same structure so that you get a feel for each candidate. Start by telling the nanny about your family and your children, then go onto talk about the position and what you will expect of them if they are working for you. Then ask the nanny to tell you a little about themselves and what they are looking for in terms of their next position. After that you should go through the nannies CV in detail and get more information about each of the childcare positions that they have held before.
After this you will want to run through some questions that give you an idea about the nannies abilities in given situations, such as what their attitude to discipline is, what activities she has in mind for the children, and any particular questions that you want to clarify about their background.
Finally you should finish off the interview by asking the nanny if they have any particular questions for you. The position of nanny is a special one as they are being let into your family but it is still a job, so you want to make sure that you get someone special and someone that you can work with, as well as someone that is good for the children.
