erm, 7 months ago, I didn't have a clue about the job I'm doing now - I had life experience, transferable skills, and a willingness to learn though.
It's a catch 22 - you can't get experience without the job, and you can't get the job without experience.
Luckily some employers are able to see a persons potential and give them a chance.
Do some research on the company, and their client group before the interview, express how keen you are to undergo training.
Lifeskills in this situation are normally things like cooking, healthy eating, budgeting, etc, advice could be anything from helping to sort out benefits, filling out application forms or applying for jobs.
It's mostly common sense and you can learn quickly if it's in your nature to want to help people less fortunate.
Like I said, I had zero experience before starting my role in May last year, but within 2 months, they gave me extra responsibilities.
