Behavioural (STAR) type questions. Questions about work experience and ones designed to determine cultural fit.
Typical of what you would expect. For example: Why do you want to work for us? Give an example where you had to overcome a difficult task as a part of a team? How are your skills relevant? What is your career path? Etc
How do I deal with change? What would I do if there are no guidelines with the work I am doing? How did I overcome a mistake I made?
I was asked about team work, how I've handled difficult decisions and giving bad news. Also, how I would define professionalism.
Mostly things about my work style, and my motivations for wanting to work for the government, with an emphasis on approaches to working in a team.
