As with every skill you’ve ever learned, you have to learn a technique and then practice, practice, practice!
A mock interview will not only help you perfect your technique, but it will also allow you to get valuable feedback and coaching on your performance. Working with a professional and getting feedback on your performance in a mock interview is similar to working with a sports coach to learn how to improve your game — both will enable you to learn where your strengths lie and where you may need work to improve your performance.
Time spent practicing will assist you greatly in either situation. An added bonus to preparing and practicing is the self-confidence you will gain.
In today’s competitive job market, you must be prepared and in top shape.
