Just go in on the assumption that you only narrowly missed out last time, and some other consideration, whether a new opening on a similar team, or the previous candidate not working out, has left you in a good spot. It’s been a while since I was doing any hiring, but I often had to pick between people with similar credentials and similarly good interviews. I had to pick somebody, but I would have been happy taking my chances with either candidate and would have been quite relieved if they were still interested when the position opened back up. From the other side, when I first started at my current company, at least four or five of us came on to do the exact same job within a few months of each other, and the difference seems to have come down to how busy the hiring manager was when they first got the budget to bring someone on.
