How can you help Volunteer Volunteering FAQs Will I need to attend an interview? For retail opportunities, volunteers can go into one of our shops, or our distribution centre (warehouse) - the manager will offer you a taster session. If this is successful, you should be able to start very quickly. You will need to be able to provide us with references. For all of our roles an interview is essential as we sometimes have many people apply. If you have added other roles you are interested in and you are unsuccessful in your first choice we will try and match you to another suitable role.
