If I were hiring you, I could care less about a year gap in employment. I'd probably be a little jealous is all, lol.
Interviews are odd. I'm honestly a terrible interviewer, but a good employee. And I've had plenty of people who interview great, but suck on the job.
I interviewed for a high level job at a mixing company some odd years back, and I was being interviewed by the entire board. The owner pulled out a little diorama and started asking me these really odd questions like "you're walking through the woods, and you see something shiny in the dirt. What is it?". I thought it odd, but by question number six I stood up and said "You know what guys, this job isn't for me. And the shiny thing in the dirt is supposed to be money, right?" They said yeah, you sure? And I said: Yup, and walked out. Was never upset I did. I'm down to do work, but I don't need to be psychoanalyzed by some rich turd, lol. I've heard since they've been through like 5 people in as many years in the position....
So stick with it. You'll find something great. The best part about being unemployed is there's nowhere to go but up.
