[单项选择] Companies sometimes receive hundreds of applications for a single job, and it is becoming more common for managers to conduct screening (筛选) interviews over the phone. This saves them considerable time and money—especially if a candidate lives out of town. Don’t take these interviews lightly. It is important to prepare for a telephone interview just as you would do for a regular interview. The employer will normally call or e-mall you in advance to set up an interview time. If possible, arrange for the interview to be held over a landline phone(座机), as it is more reliable than a mobile phone. Make sure that children, pets and other sources of interruption will be out of the room. Keep a glass of water nearby. Phone interviews can often last a half-hour to an hour and be sure to have your résumé in front of you. Do your best to be personal, but don’t overdo it by, say, trying to tell a joke. What should you do with your rétsumé during a pho
A. Keep it in front of you.
