The company going to conduct your phone interview will inform you about a particular day for this activity. You should take out some time and set up the place where you intend to talk to them. Make sure you have your privacy there as these calls come when you are not expecting them.
You should have a pen and paper to jot down the important points along with a copy of your resume so you could explain your achievements in detail.
Ask your kids and other family members to note down the contact number and the name of person if the call comes in your absence.
You should carefully choose the place to attend call interviews as a noisy place can cause distraction while your interview is in progress.
Only accept the telephone interview option if you have adequate time which should be around 45 minutes. If you do not have much time or you are busy in some activity ask your interviewer if he/she could call you at an appropriate time.
Make sure your throat is clear and you have a clear voice as otherwise your interviewer will be uncomfortable.
Remember, your ultimate goal is to pass the phone interview so you could be shortlisted for a face-to-face meeting.
After you are done with your interview, you should dispatch a thank you message to your interviewer as this leaves a positive image.
