When an construction interviewer asks you why they should hire you, you're going to have speak confidently and honestly about your abilities. But you should avoid sounding overly boastful.

Aim for earnest and prepare by practicing. That's right: Stand in front of the mirror and acknowledge your abilities and accomplishments to your reflection. Tell yourself: I have a very strong work ethic. I have integrity. I have excellent construction industry contacts. I aggressively pursue my goals.

It's sometimes hard to praise yourself, but after a few sessions you'll sound sincere.
