To sound professional, it helps to:
- Stand up so you remain alert and focused.
- Speak clearly so they hear your entire response.
- Smile because smiling makes you sound warm, friendly and approachable.
- Dress in interview clothes to achieve a confident, professional manner
- Avoid chewing gum, coughing or clearing your throat directly into the phone. It’s always better to excuse yourself for a minute if necessary.
- Practice beforehand with friends or family members.
