Failure to develop an up-front contract with the applicant. Many interview sessions lack structure and focus. If the ground rules of the job you are hiring for are not established at the start, then the interview cannot be successful. Failure to get a decision from the applicant. Model strong selling behavior and get the applicant to make a resolution.
Decision makers get others to make decisions.
Failure to deal with guidelines concerning firing. Sales Managers spend a great deal of time telling applicants what qualities and abilities do fit the job's requirements but neglect to outline the criteria for dismissal. Although it will not relieve the pain of termination, the candidate's understanding of what actions are grounds for dismissal is an important element of the interview process. In addition to saying what qualities you are seeking, also tell your applicant what the job won't tolerate. Failure to tell it like is.
