I was just getting over pneumonia for my first interview (1 day into my antibiotics), and I must say if you have the option to reschedule, do so! During the interviews I constantly had to focus on not coughing up phlegm all over my interviewer, and that led me to: 1) fragment my answers 2) sometimes lose focus on the questions being asked or my own responses 3) cut my answers short. To add insult to injury, mid way through the day, my voice started getting hoarse, then it just started going away...disaster....
