National Association Of Counties interview questions

Interviewed by two people for first round. Fairly relaxed and straightforward interview. Asked typical interview questions about my experience and questions pertaining to the role. I didn't get asked for a second interview, which is fine and expected with how many people applied (70+), but it's always a red flag to me when companies don't even bother to send a rejection email. I've taken time away from my current job to meet with you and I can't even get the generic, fill-in-the-blank "we're moving forward with other candidates" email? Wasn't the opportunity for me but an overall average experience.
