Job interviews are the first personal interaction between the company and the applicant.
During the interview, the interviewer tries to find out whether the person possesses the required job skills as well as the required personality.
Being a humble personality is just one of them. Always remember that honesty is the best policy, whether it may be in one’s personal life or professional life. If you are ever asked a question whether you are overqualified for the job, you should remember that this is a rhetoric question, and the actual answer depends on your qualifications and the job requirements.
Also, while answering this question, you should understand that this is the era of multiple capabilities in every professional. Therefore, the job may be making complete use of one part of your capabilities and ignoring the other part of your skills/capabilities.
If this is the case, you should put across this point to the interviewer at the right time, and mention that though you may be overqualified for the job due to one aspect, the job may be the best way to learn new things as per your secondary qualifications.
If your qualifications and past experience give the idea that you are overqualified for the job, it would be a good idea to accept that it is – you can give reasons as to why you are applying for a job that does not take full use of your qualifications.
