Beatrice - the key to interviewing is to let the person speak.
We often get so caught up in asking questions and them answering, but it often does not give them time to really tell you anything.
I prefer to keep questions quite vague and then let them talk.
Tell me about what you did in your last job?
(Initially the answer may be - I looked after children - but then push it and say, explain your day, you woke up at what time and then what?)
Ask them a key question - what did you do when baby was sleeping?
What did you feed the baby - did you make the food, explain what happened.
How did you cope when baby was sick? Tell me what happened when baby was sick - how did you take a temperature etc.
What happened when the mom came home?
What is the part you enjoyed/what part did you least enjoy?
I found it easier to focus on a job they have and push them to talk around that - rather than ask inane questions.
Finish the interview with:
What salary are you looking for? (Even if it is on the paper in front of you, ask it and discuss it.)
Ask if they have children - who looks after them? Be sure you understand what the family responsibilities are - this often falls to the women in a family/house hold even if they are working.
Legally you can ask if they have had an HIV/TB test - you cannot make a decision based on the results (no seriously)
You can also ask that part of this job is that they go for a screening which you pay for.
Make sure you get at least 3 references.
Ensure you clearly understand why that person is on the job market.
Legally you are entitled to do a criminal check.
Try your best to ask questions that just get them to talk, try to sit there as best as possible and say nothing - the more someone talks in an interview the more you can gauge from them.
Listen to you red flags - listen - often things will go off, and we then excuse them. The red flags are your warnings. Listen to them.
The only notes you should make are - name, cell number, availability, suburb where they live, how they will get to work, how long it takes them etc.
You should have a copy of their CV to work from. (please remember everyone is desperate to find a job, so ensure you listen and tryst that feeling you have)
Good luck - finding someone is really hard.
