There was nothing wrong with the way you interviewed, but the other candidate was an office manager/rocket scientist/could pull rabbits out of their arse??!
How do you get a half decent job when you've been a sahm for years and all your other jobs have been in retail/childcare?
I'm a bright person but I had my ds young after only having had student/part time jobs, I now live overseas where job opportunities are few and far between and it's a nightmare getting your child into a nursery.
I'm doing an ou degree and want to train as a teacher afterwards but I have this awful feeling that they are going to look at my empty cv and I'll get rejected for everything!
You could try working for yourself. If you want to be a teacher and are doing a degree, could you tutor children, or childmind just to get experience? Or set up an after- school club in art or cookery - anything you feel comfortable running. It could make your CV look stronger and would show you have initiative and genuinely want to work with children.
Yummy, you say you want to train as a teacher. How about the experience of running your own business selling children's books (0-16yrs)? You don't say where overseas you are, but message me if you're interested.
Oh and did I mention there are no childcare costs?!
