Just be straight with them and answer the questions as truthfully as possible and also wear something casual clothing and have a good attitude and they also want to see that you have a good attitude

They asked a lot of yes and no questions, but don't just reply a simple answer...say yes i able to work in all-weather condition and i understand that's part of the job, they ask what's your strength and weakness, or what would you do if you see someone who's not following the rules, and tell me a time where you have to deal dangerous or not so well friendly worker, last at least they ask how important is communication, etc...
