Well the interview went very well. I was nervous as hell in the lead-up to it, but I calmed down quite nicely in the few minutes before I was taken inside. The interview seemed to go well. I was given some background about the company and the project before being asked to talk through my CV and how specific skills would apply to the role. Then asked some more probing technical questions and some general competency questions. The format was quite relaxed, almost conversational, so I didn't feel too bad talking about myself and my achievements – it didn't feel like boasting.

Initial feedback from the agency is that there's another candidate to interview on Monday, but that they're "very interested" in me. So by next Wednesday's meeting I might even have a job offer on the table, which would be nice.
