Going out to Washington was cool. I got to meet up with Josh Petrie for dinner a few nights, and I liked the area from what I was able to see of it. ArenaNet is working on some cool stuff, and it'd be great to finally be able to say that I worked in the games industry.
On the other hand, Microsoft has a pretty impressive campus, and the list of perks and benefits is pretty big. It's hard not to get caught up when you're interviewing for a team of several thousand people, all of whom work at a campus that sees 30,000 people working there every day. I interviewed for the Office Exchange team, which isn't exactly the area I'm most interested in, although it was nice to see that most of Exchange is now written in C#.
If I get an offer from both places, I'm still not sure which way I'm going to go. This is only for a 12-week summer position, as I still have a year of school to finish afterward, so there's a lot to take into consideration when making the final decision.
