The number of emails I have gotten announcing information meetings and tech talks hosted by companies looking to hire people from my CS department is way up this fall. I think it's easily back to spring 2007 levels.
Obviously this is entirely unscientific, and there are tons of confounding factors (has getting these announcements forwarded to the appropriate mailing lists gotten easier lately?) but it's still an optimistic sign.
PS Still very few people looking to fill faculty positions, by my feeling. Industry all the way.
PPS I've only attended a couple of events since I'm still a ways from being graduated, so I have an even smaller sample size, but some of these companies have no idea what they're doing. Even Google's latest recruiting talk was terrible. I'm hoping the tech talk from one of their researchers tomorrow will be more interesting: Vahab Mirrokni on "Algorithms for Online Stochastic Ad Allocation"! Sign me up!
