If you don’t hear back after an interview, don’t panic. There are several reasons hiring managers don’t get back to job applicants after interviews, including:
They are busy and haven’t had a chance to reply right away.
They are still interviewing other candidates and want to create a list of their top candidates before replying to anyone.
The job has changed or been eliminated for various reasons.
Someone else jumped out at them as the best candidate, and they hired that person immediately. Better luck next time!
