Every applicant that goes through your application and interview process deserves to be treated with dignity and respect. Never forget that every communication you make on behalf of your organization sends a message defining your organization in the public’s perspective. Make sure the message you send is consistent with your organization’s mission and values. In crafting the letter, it’s generally best to give a neutral and non-specific reason for the rejection. No employment law requires you to tell employees the reason why they were not hired, and you do not want to get pulled into a debate over your specific reasons.
