I recommend you take time this week to practice your interview methodology and cadence. Go so far as to prepare the meal menu you will eat before the interview to have all parts of yourself ready to hold the discussion.I also recommend you do not multitask during the interview discussion. There is nothing good that comes from multitasking during a crucial discussion. All that is demonstrated by multitasking during a crucial discussion is chaos is present in your organization. If you need to communicate to the candidate you have chaos in your organization, then you can do so effectively by way of a single sentence, either verbally or in writing. Then, stop multitasking and focus on having a productive conversation.
