okay I had an interview for a big company and although I don't think my answers to their stood out as much, I think my intro and the questions i asked at the end weren't that bad + i think i showed my authentic self and connected as people with the interviewers. while i was leaving at the end, one of them told me not to worry if they don't get back within a few days because the process is slow. initially, i thought this was leaning towards more of the optimistic side, but after some days talking to people and interview experiences online, I'm now thinking that this is basically a soft way of indicating a rejection (e.g. hr will contact you). now im having doubts that the parts i thought were good were just bad and my interviewers had already made up their mind

can i have some input on this? thanks
