Hi eve, at a recent interview I went to, I asked towards the end of the interview about hours (I wanted to know what their views were on flexible working, working from home occasionally, etc). The HR person on the panel ran through the contract T&Cs so that was an ideal time to task. If you are going to ask that question, you need your rationale ready as to why you would like them to consider that option, what benefit it would be to them. You could also think about a 9-day fortnight, spreads the hours differently?
