<prompt> Human: What is the most respectful way to reject that seems like a harsh word to use a candidate that you have interviewed for a job? A phone call? An email?  <response>: Honestly, when I was interviewing, I preferred someone calling me. I didnt have an issue with places sending an email, it just got a little insulting when they were machine generated emails. That being said, I think the absolute nicest thing you could do would be to tell them why you didnt hire them and may let them know what they could improve on. I tried asking most recruiters this and they wouldnt tell me.
