honestly acknowledge skill deficiencies and decline to interview for a position until all skills are achieved.

proceed with the interview and emphasize the skill set the candidate has actually achieved.

disclose any skill deficiencies and present a plan to meet those deficiencies.

proceed with the interview without disclosing deficiencies but make certain that all skills are met prior to hire.
