I emailed you. In summary: I don't think I'm capable of passing an interview atm, certainly if (as I presume) your place is good. But we can discuss, at least.
Yeah it's IT rather than being on a desk, maintaining back office systems largely.
I have been working on my skill set, I know C# pretty damn well, I have taught myself aspects of software engineering + computer science I didn't have, etc. etc. - it's just that there are gaps, lots of gaps and more than that, a complete lack of confidence. This stuff grinds you down so much that it becomes very hard to resurface, that's part of the problem.
I am working hard on filling those gaps, but I think it'll probably take a year before I've sorted it. I went for a bunch of interviews at other finance places recently and the gaps were exposed very clearly there, so this is based on evidence.
Anyway, I don't want to talk much more about this unless stuff starts becoming toooo identifiable.
I work at a small hedge fund in London, started on £28k (actually might have been less, I literally can't remember now), after 4 years I am up to £40k, with around £5k bonus each year.
I have basically been doing CRUD of various flavours the whole time under a bullying atmosphere, utterly soul-destroying and it's got me stuck in the Stockholm syndrome scenario, my skills ground down to the point where I literally can't get another job to get out of it. Am working very hard to counter it, but it's a big job, probably another year of work to stand a chance of getting a decent software job (I'm not going to try for another internal finance job, if that sucks as much it'll be pretty impossible to bear).
So yeah, I don't recommend it, though it might just me having bad luck here.
I think very few internal jobs, finance included, are even vaguely bearable for hackers - I heard the idea that finance likes to hire overqualified people for monotonous/trivial jobs to make sure they're done right, so you have to be really careful.
