Thanks for the advice. I did a bit more research on the job, and found out exactly what I would be doing.

I've been paging and working through a couple books I picked up at the library the other day - one on ASP.NET and the other on C# (the principal languages of the job). They've helped clarify some of the technical and syntax differences in the languages, but so far (not too terribly far in either one, mind you), C# reminds me a lot of Java. Very similar in structure and OOP functionality. ASP.NET runs very similarly to the way PHP does, but it's a bit more lax. There are also tons of resources available online.

I think my interview is next week. I'm not too worried, I'm confident in my abilities in my current languages (PHP, C++, Java, just starting to pick up lua), but that job pays more and in a location that would make the wifey awfully happy. I just hope it's a reasonable interview. I had one once where the guy wanted me to code, in my head, on the spot, and spell out in syntax how I would write a method to solve a problem. Ridiculous.
