Treetops Nurseries interview questions

Welcomed immediately by a friendly manager. Asked about myself, previous employment and my expectations of working for the nursery. I was briefly shown around the nursery to get a feel for the environment and briefly meet the staff. I was offered the job pretty much immediately (they were desperate for staff) and told my DBS check would be covered by the nursery. However, on my third shift I was called to the office and asked if I would like to pay for it myself in instalments or in bulk!
