Most of the time, a phone interview is unannounced. You just get a call one day and before you know it, you are already engaged in a phone interview. That is the main reason why you have to be always prepared.
Here are some expert tips to increase your chance of passing a phone interview:
1. Use a landline instead of a cellular phone. A landline is more reliable than cellular phones so make sure you use one to conduct the interview as smoothly as possible.
2. Avoid distractions. Find a quiet place for the interview so you don�t upset the hiring manager by unwanted noise.
3. Relax but remain focus. Though the person on the other line cannot see your facial expressions, it is important to keep your calm so you could concentrate on answering the questions intelligently.
