I once interviewed with the 4th largest city in my home state for an engineering position. I think this was the first interview. I sat at one end of a very large table with I'm guessing 8 or 10 city employees around the table. I had about 5 or 6 years experience from field to office after undergrad. They basically played 20 questions with me taking turns asking me questions that I might know nothing, very little, or a lot about. I believe they were surveyors, inspectors, engineers, and maybe others. I basically just answered them honestly as I could. I got to do a second interview with 2 people being the manager at that time and one of his underlings. It seemed to go well but one of my questions for them was if they wore those ties on a daily basis and they answered that they did for public appearance. I can't remember too much after that because that wasn't for me.
So I would imagine you will probably get fairly thorough breadth of knowledge questions and maybe a more limited depth variety of questions to answer being that it is an entry level position.
