Gather information about the organisation:
First thing you should do is to gather information about your potential employer. You must know what type of company it is and what the work culture is. Moreover, you should check the job description and make note of all the required skills. You should construct your conversation in light of these details. Use as many keywords as you can because this leaves an impression that you understand the company and the job offered by it.
Make a list of potential questions:
The best way to be prepared for a telephone interview is to make a list of potential questions and prepare some valid answers. Mostly, interviewers ask about your educational and professional background, your achievements, failures, strengths and weaknesses. You should be honest in answering any questions.
Make yourself comfortable:
You may face problems in understanding the question if it is your first experience to be interviewed over the phone. The best way to avoid such situations is to practice before the actual interview. Ask your friend or family member to conduct a fake interview. However, take it seriously otherwise it will be a futile exercise. Request them to ask question not only from the list but also include some surprise questions. This will help you to handle any unexpected situation in the actual interview.
Keep your resume in front of you:
The most common mistake people make is to forget the information they provided in their resume. To avoid an embarrassing situation, you should keep your resume in front of you. This will help you to answer all the questions according to the information provided earlier.
You should be extra courteous to make a good impression on the interviewer. Keep a polite tone but speak loud enough to be heard.
