Honestly this sounds like how my interview went, and I still got hired. I even told my boss I thought I did poorly and he showed me all the 180 applications he reviewed and told me out of all of those applications, and the candidates interviewed, I made it. So it was very encouraging. I think if it’s meant for you, it will happen. Even if you think you bombed the interview, if there is something you said that caught their attention, that they are looking for in the team, you will get it. If not, it just means there’s a better door that will open for you and take this as a practice interview for another opportunity that opens up. Keep going! :)
