Douglas County Sheriff-Oregon interview questions

I applied online in June. I was emailed about a "pre-screen" interview which took place in August. I was escorted to a room where one person sat across a table from me. He asked me a few questions including: have you ever had a traffic violation including misdemeanors, have you ever used illegal drugs, have you used marijuana in the last 5 years, have you ever been arrested, and a question that basically asked have you ever been a party in a legal process where you were accused of something. There were a few other basic questions as well. I was informed by email a few days later that I had passed the pre-screen interview and was now eligible for the written exam. I took the exam which was mostly about spelling and punctuation. It was scheduled for an hour and you had to complete roughly 150 questions. I was informed by email a few days later that I had passed the written exam with 95%. I had an interview today (August 19, 2014). I was escorted into a room where 6 people waited to interview me. Two of the people were uniformed police officers and the 4 others who looked to be office workers. I was asked: first to describe myself and my goals, why I want the position, why I would be a good fit, if I have ever been forced to leave an employer, if I have ever been written up at a previous employer, lastly, they asked if I had any questions. It took about 10 minutes. It was extremely uncomfortable but I guess that's to be expected when your interviewing for a Sheriff's Office. I was not completely prepared for some of the questions they asked but hopefully that isn't a total dis-qualifier.
