This question is often asked of younger people who have just left full-time education. No employer wants to hear that you are completely inexperienced, even if you only left college a week ago. If you took part in any practical placements at college, talk about them here. You will need to come up with some kind of answer in order to reassure the interviewer that you are used to the routine of work, that you can hold down a position and that someone else has wanted to employ you in the past. Perhaps you have done a paper round; worked on voluntary projects while at school; had holiday or vacation jobs or participated in a work experience programme at school or college.
If you have never done any type of work at all, do not let this situation continue as now is the time to start. You could offer your services to a community organisation on a voluntary basis or ‘work shadow’ some friend or relative who does what you are interested in. A training course could help you pick up many transferable skills. If you are studying it may be possible to get a Saturday or evening job. Apart from providing you with a positive response to this question, and giving you added purpose and contacts, the work experience may enable you to gain a character reference from the organisation concerned. Voluntary or temporary work can also show you whether you would like a certain job or not by giving you a trial period to see what it involves.
