In Daniel Pink’s book: “When”, he discusses at what point during the day most of us are happiest and more warm to others.
Based on his research, the mid mornings are when the “feel good” mood peaks and again right after lunch, troughs in the afternoon, then picks up again in the evening (assuming the work day is over).
If this has any indication on scheduling an interview and you have a choice, you might want to shoot for 9 AM, 10 AM or 1 PM.
Or again at 8 PM.
Keep the advantage on your side, when possible.
