Do not be afraid to ask questions.
"Will I be working residential or commercial? How many are on 'the crew'?
Interviewers like having candidates ask questions rather than sit there like a lump on a log.
Do not lie about anything. That would be a death knoll. If there's anything in your past/background/work history that you're not proud of, be honest and forthright about it. For instance, let's say you have a drunk-driving charge on your record. If it comes up, don't shy away from it.... and make sure they know you have paid your fine, gone through the program, you've proven yourself enough to get your license back... in short, your debt to society has been paid and you want to move forward.
Remember, you're interviewing for a job, not standing before St. Peter at the Pearly Gates. The sun will still come up tomorrow no matter how you did. Life will go on. And if it doesn't turn out the way you would like it to, chalk it up to experience, take what you've learned and keep at it. Perseverence pays.
And lastly, please, I beg of you on behalf of everyone here......
let us know how it comes out!
