I have been vacationing a while lately, and may have a couple interviews in the near future. I want to brush up on my C++, as it's been some time since I did any professional programming. Any advice on good advanced tutorial sites or (adaptive?) quizzes? Also, as long as I'm here, anyone have any recommendations for international recruitment sites? Mostly have been looking at large companies' postings (IBM, Microsoft, JP Morgan, etc), but maybe there are other resources out there I haven't yet considered.
In the past I've been contacted by a couple of big recruitment agencies because of my ranking on programming competition sites, specifically TopCoder and SPOJ. You have to have a fairly decent ranking though.
