A question in an interview for janitor post was , which place in the building would you think was most important that it kept clean and tidy .He said toilets would you agree or would you have said somewhere different .
On second thoughts it depends on the premises. My response would be,"Whatever experience dictates. Let's have a look round immediately and I'll then give a reasoned answer". And I would then put my foot down and insist upon it to help me decide to take the job should it be offered. From my extensive experience of job interviews that should put the cat among the pigeons LOL.
