I'm applying to multiple IT jobs in local government cities. I've never been to a government job interview so I don't know what the etiquette are. Not even sure if my resume was suppose to be any different that a private company. Do they ask the same basic questions that most private companies ask? I just want to be prepared during the interview.
It can depend on location, but in general there is no difference. I have found govt to be more strict on qualification requirements, but that's about it.
Private company interviews aren't all the same, and I would guess the same applies to government jobs. So I don't think there is an answer to your question. There may be regulations that apply to the position in the government job, but I have also worked in several private companies where there were significant government regulations that impacted the job.
Ideally the interview should be about your ability to do the job, regardless of the type of employer.
