Yes… you read correctly. Preparation for an interview consists of making sure you attend to your personal health needs in order to be comfortable during the interview, especially if you have a diabetic condition.

A true story:

While interviewing a prospective candidate for a position, the candidate stated she had not eaten and was a diabetic. The candidate was given the opportunity to leave, get something to eat and come back later. The candidate indicated she would be okay and the interview continued. Based on firsthand knowledge of a diabetic condition, candy was offered to help with her comfort level. The candidate accepted the candy. A few minutes later while the interview was still in process, the candidate looked down into her purse, said, "Oh, I have some Fritos" and proceeded to pull them out and munch on the Fritos during the interview and didn’t even offer to share.

Eating during a interview sends a negative view of the prospective candidate. Along with things "Not To Do" in an interview, the candidate also did not take the responsibility to prepare for her own well-being. This leaves the question of how will the candidate prepare and function in job responsibilities.
