Applied at Company X for Unknown

I had an interview with Company X about a month ago, which included a session with HR and another with the hiring manager. I felt really good about how the interviews went, so I was quite surprised and disappointed when I received a rejection email from HR. The email thanked me for my time and stated that they had chosen to move forward with other candidates whose experiences better matched their current needs. They encouraged me to apply for future opportunities, but it still stung. Now, I'm contemplating whether I should reply to the rejection email. I usually don't respond to rejection emails since I know it won't change the outcome, but I invested a lot of effort into this process, especially since I got the interview through a referral. I'm starting to feel like this whole experience might be overrated.
