I had an interview last week and it went pretty well. I was on the same page with the interviewer that the position would be filled by January. I promptly sent my follow up thank you emails to both of those in the interview but I've only heard back from one. Unfortunately the person I heard back from isn't the one with the hiring authority.
It's been a week since my interview and I still haven't heard back. Do I follow back up? At what point should I check in?
