I had a job interview for a role I'm highly suited for, with some niche experience that I imagine few applicants would have. It's a competitive position, and they would have had aa large number of applicants. When I applied, it mentioned the role wouldn't need to be filled for a couple of months but the interview was arranged a lot quicker than I anticipated (within the week). My references were contacted. The interview itself lasted longer than expected although I don't think it went well. I was nervous and couldn't answer some of the questions as well as I would've liked which might have made me seem not knowledgeable. At the end, one of the interviewers from the panel said, "Good luck." does this mean I didn't get the job?
