I don't want to burst your bubble, because I would absolutely feel great if I were in your shoes, but I do want to warn you to temper your expectations so that you don't get depressed if you don't land the job.

I had an interview almost exactly like that about a year ago and fully expected to land the job. Unbeknownst to me, the only other person they interviewed for the position turned out to be far more professionally qualified (they basically had 5+ years of experience with that exact job in a more rigorous environment.)

Point simply being, you may be perfect for the job and they may love you, but it's never entirely in hour hands.

Either way, good luck tomorrow!
