Tell the interviewer how many days of work you missed in the past year. Keep in mind that taking a vacation day does not count for this question, so there is no need to share these days when answering the question.
Missed only a couple of days? No problem! We are all human, and sometimes we need to miss work due to our own illness or the illness of our children or family members. Simply tell the interviewer that you missed only a couple of days, and your previous employer would say you are very dependable.
Missed a week or more? You should be honest during the interview, and tell the interviewer how many days you missed. Hopefully, you missed them for good reason such as having surgery, a spouse having a baby, or being with a loved one during their final days. If this is the case, share the information! It provides reputable data for why you missed a significant number of days and will not hinder you from being considered for the role.
