How to reply if an construction employer ask "Do You Have Any Questions for Me"?

You should always try to ask a thoughtful question or two at the end of an construction interview. It shows that you've been listening and that you've done your research on the construction employer. DO NOT ask about construction salary, vacation days, benefits or anything else that would make it look like you're more interested in the compensation package than the construction employer. Also, don't ask too many questions; just a couple will be fine.
And the most important question of all: Don't forget to ask for the job!
