So I had a friendly chat with the recruiter. I was surprisingly alert and responsive despite it being so stupidly early in the morning (~5:45AM) my time. The job seemed very doable, in a nice area of London that I know pretty well, good package, etc. He was taken aback by how little time off I received which made me laugh. Me being overseas didn't really bother him at all. I'll have to research the company some more.
So, we'll see....
