Try to ask questions which will facilitate discussion. Avoid questions which only require a yes or no answer. Don't ask leading questions. Keep the questions open ended so that the employee has the opportunity to speak freely. Be sure to ask only job related questions.
Listening skills are essential in an interview.
It is important to let the applicant speak without being interrupted. Remember, the purpose of the interview is to obtain as much information as possible. You are not obligated to interview every person who applies. Select the best qualified individuals for interview, based on applications and resumes. As a matter of courtesy, please keep all interview appointments you set up, and follow up each interview with a letter after a hiring decision is made.
