Diligent interview questions

Did two rounds of interview, one with the Talent Acquisition and the other with a Director on the team. All the interviews were pretty much genaral questions about experience and all that. Both interview went really well in my own opinion, but i got a rejection email without any reasonable feedback. Just the lazy generic "we are looking at other candidates whose background and skills more closely meet our needs".

Provided my availability for multiple slots but didn't receive any meeting link/email about when to have the screening call until a few days later when I updated my availability to one specific date but then they scheduled for the next day instead which confused me but ok not a huge issue but already made me qs their level of communication. Then the HR/talent/people person was 10mins late or more, which can happen I understand, but they did not apologise and continued as normal so that made me feel icky. 1st stage with the hiring manager was fine, it was easy to talk to them but by the end they did not do a wrap up of next steps/when i can hear back until i asked and they just said "the people person will get in touch with you" - did not disclose the timeline so that felt a bit awkward. Had a feeling it will not progress because of that - and it didn't.
