In addition, a few people back out of positions after being selected. In addition, a number of positions are canceled for one reason or another. If at all possible, get at least one reference from an employer for a paid or volunteer position. Other good references are faculty or other professionals who know you well. Do NOT use family friends.
Telephone interviews play a major role in deciding who is offered a position.
Make it as easy as possible to set one up with you. Treat one as you would an regular job interview. Review the job description and required qualifications before the interview so you are prepared to explain why you are the right person for the position. Ask questions that show interest in the site and position. Finally, if you plan to apply at some point in the future, consider ways you could upgrade your competitive standing between now and then.
