For the interview, preparing and having a positive mindset is essential. The more confident you are the better you’ll perform. To boost your confidence, look back at your new résumé and the great things you’ve done. Also, ask yourself: Why do I deserve this? How have I added value? Come up with strong answers to both those questions ahead of time. You want to have three solid sound bites at the ready, and make sure you squeeze them into the conversation no matter what the interviewer asks. It can be about your wins, about why you want this promotion, or the added value you provide to the company if you are promoted. You can even ask your friends to mock interview you so you have it down.
