What certifications do you have that qualify you for this position?

Many professions require certifications. These validate that a candidate is qualified for the position and has acquired the appropriate education and training to work in this job. While not every employer requires a certification, having them will distinguish you from the other applicants and encourage the hiring manager to review your training, skills, and experience. Many employers will acknowledge your progress towards a certification even though you haven't received it at the time of the interview.
