Ideally you will want to reach the person who interviewed you, but if you can't, feel free to leave a direct but polite message. If you don't hear back after a few days, don't give up and persist. You have nothing to lose, so pick up and call back. Worse yet, you should at least send the interviewer an email expressing your gratitude for the time they took to speak with you. If an employee responds to you, but with concerns rather than praise, don't hesitate to talk to them about it right away. Practice, practice, practice. The ultimate advice that anyone can give you regarding job interviews is very simple, you need to practice, practice and practice some more. Practice with family, practice with friends; practice with a professional, practice on your own, but just make sure you practice. The reason to practice is important because working on the fly during an interview will ultimately lead to disaster for most. It is also through practice that you can improve, enhance and revise your interview technique for the current interview.Final
