What are some good phone interview tips?

I am going into a telephone pre-screen construction interview so what can I do to assure a successful phone construction interview? It’s important to schedule an construction interview when you are not distracted. Get In a quite place where you can concentrate on what is being said and what you are saying. Try to get to a hard line to avoid cell phone static or dropped calls. Speak clearly and slowly into the phone, and smile often. The smile is said to be communicated through the phone and an upbeat attitude is contagious. Have prewritten questions to ask and review the job spec so you know what questions are likely to be asked. Sell your strengths, but focus on the three or four most appropriate strengths (not all of your strengths) so as to generate the most memorable impression of your strengths.
