If you are given the opportunity to ask questions at the end of the job interview, I would encourage you to do so. Look at the information you have received about the role and try to imagine yourself starting out in that role. What questions could you ask that demonstrate your interest in the role? Make sure your questions don’t show up your ignorance about something you should have been able find the answers to yourself. Interviewers will expect you to have done your research. Quite often, in public sector interviews for general grades (where there is no job description really, other than the definition of the competencies, such as for Executive Officer) candidates don't ask questions. The same is true for internal candidates, who mostly say they don’t have any questions to ask and that’s ok.
Some questions you could ask are:
Is this a new role?
How many people are working on the team?
What training would be put in place for the successful candidate?
What would be a typical day be for someone in this role? or
What do you like best about working for this organisation?
You are always safe to ask:
What are the next steps in this process? or
When will I know the outcome of this interview?
