If it is a phone interview, it's usually with a PR person who knows very little about the position and technical terms related to a specific job. Make sure to use keywords and buzzwords while answering questions because you are trying to paint a picture with words, since the interviewer has no visual clues of you. Do this and you will pass the phone interview.
- Treat the phone interview like a real professional interview. Go to a quiet place, don't get distracted or do anything else but speak, and talk slowly and clearly.
- Keep your notes in front of you, but still be prepared to talk on the fly. Having your notes can make you feel more confident about what to say, but don't lean on them.
- Dress for business. Dressing in a professional manner will make you feel more prepared, than if you do your phone interview in pajamas or shorts.
