If well done, however, they will open doors for you to proceed to the interview process. Keep in mind that, during any interview, you are being evaluated on more than one level. Besides your actual job skills, an employer will evaluate intangibles, such as your enthusiasm for the position, body language, eye contact, energy level and communication skills.
