Consider adding a bio or profile to your professional correspondence. A bio or profile can serve as a complement to your résumé, as well as be utilized to expand your on-line brand, for example your profile on LinkedIn. Many job seekers do not consider the importance of social media, and as such they lose out on the opportunity to complete their overall brand identity. Make no mistake - the interviewer will check your on-line profile, therefore it is critical that you present a well thought out image.
