Thaneofharmon's journey

I recently had an interview for a promotion at my company where I've been working for nearly three years. A few days ago, I met with the interviewer and our HR representative to discuss the role in more detail, which led to the formal interview. During the interview, I felt that my answers were not great, especially in the first part, but thankfully that was only one-third of the interview. By the end, I felt more comfortable and had many of my questions answered, even going over the scheduled time. Now, I can't help but wonder if I overthought my performance or if I really blew my chance at the promotion. I'm seeking advice on how to handle this waiting period and whether I should be concerned about my interview performance.
