In my experience, I dress up for the role I am seeking. When I look for a warehouse job, I wear jeans and a collared shirt.
General first questions:... (be honest with your interviewer)
What made you interested in applying with our company?
What are your strengths? What are your weaknesses?
Why are you leaving your last job? Why were you let go from your last job?
What are your hobbies?
Where do you see yourself in 5 years?
I hope this helps.  more
