Is it right to label a candidate as “OVERQUALIFIED” and reject him at an interview even before his skills are tested?

The candidates for a job role are labelled as overqualified due to various internal and external factors and may not be limited to the credentials of the candidate alone. The educational qualifications and experience level of the candidate are just one side of the coin.
In some cases, the direct reporting line may not be as qualified as the candidate himself and therefore to avoid complexities within the department and to protect the less qualified staff, many managers tend to sideline these overqualified candidates.
In terms of cost per hire, yes, these overqualified candidates can come as an additional cost to the HR budget which can be easily accommodated with lesser qualified candidates.
In my opinion, we should be open minded to give them an opportunity and see what add-ons they can bring to the table. All that matters are the skills, will power and “can do” attitude. If the candidate adheres to the terms & conditions of employment, the nature of job offered, duties and responsibilities, then he is well qualified for the job. Qualification is a basic criteria but the skill set is what matters the most.
