Call at an appropriate time
In order to conduct an effective short telephone interview, you should call the person at an appropriate time. It is never recommended that you conduct a phone interview very early in the morning or during lunch hours.
Having called a potential employee, you should initially greet him or her in a very friendly tone and introduce yourself and the company. The next step is to seek the permission of the other person for a 2 minute interview and proceed if he or she allows you to do so. If someone asks you to call at another time, you should ask for a preferred time and do as required.
Ask for a brief introduction
You should start the interview by asking for a brief introduction of the potential employee. You may ask questions about the last academic degree of the person and past experiences, if any. It is extremely important to ask if that person is currently working somewhere or not, because that determines the availability of a potential employee.
If he or she is already working somewhere, you must ask when he/she will be able to join.
Focus on communication skills and enthusiasm
It is extremely difficult for any human resource officer to judge the abilities and knowledge of a person within a couple of minutes. Therefore, you should focus more on the communication skills and the positive energy of a potential employee.
Final interview date
If you are satisfied with the skills of a potential employee and you feel that he or she is worth an on-site interview, then you will need to set one up. Take into account the schedule of the HR department, and make sure you consult with the individual to check whether he or she is available on a specific date and time.
