Interface is EVERYTHING
Kimm Walton writes that "Interface is everything" when looking for a job. She breaks this down and suggests you manage two things: Your image and your message. Here are three ways to review and craft your image and message:
1) Make sure you have a professional (or at lest neutral) email address and voice mail message. Hotdude99@aol or email@example.com are not appropriate nor is a voice mail message that says "Hey dude, I've fallen and can't reach the phone."
2) Crafting an image requires that you figure out what you want. Self-awareness is extremely important when promoting yourself, and if you don't know who you are and what you want, how is an employer to know? Consider taking an assessment such as the Myers-Briggs Type Indicator (MBTI) or Strengths finder to gain greater self-knowledge.
3) Think before you speak. This will not only reflect your thoughtfulness but will also help you manage your 'umms,' 'ahhs', 'you knows', 'likes', etc.
