Well it went OK, the most annoying thing was probably the fact my current boss ringing me six times during the hour. For some reason, my phone kept dropping the current call and trying to ring him back, so we lost connection six times, just as I was in the flow of explaining my point.
I think I fluffed a couple of the questions and didn't really speak too much about the things I'd noted before. Had a few brain farts with words at times "One of my 'benefits'... instead of strengths". But on the whole, it was an OK discussion, if not for a little awkward at times.
He said I'd be a good fit for the role and my experience with certain software and general self-starter attitude is what has me standing out. He thought I had some good ideas and I'd work well in the team, so it all sounded positive. But at the same time, he told me he's been 'constantly interviewing' people for the last week and will do so for the rest of the week. It sounded like he's interviewing around 30 or more people which is a bit intense. I'd say there's a very good chance that there's someone who will interview better than me, so I'm hoping I stood out enough but really hard to tell at this point.
It wasn't my best interview, but I'd still be gutted if I didn't get it. He says he'll be back in touch by the end of the week so fingers crossed!
