When hiring for a position, I always phone all the unsuccessful applicants to let them know that another applicant was selected for the position. Recently, an unsuccessful applicant voiced his frustration that when I couldn't reach him directly, I instead left a voicemail message about my decision.
I'd like to know the community's thoughts on whether voicemail messages about unsuccessful applications are appropriate. Should I have instead left a message for a callback? I typically try to advance the conversation with voicemail messages as Mark and Mike's advice.
