I don't see 2 failures being the deciding factor, 3 would would be a different story. I think you just had some bad luck. Keep applying and go to a recruiting event. From reading the boards it seems hiring isn't as fierce as it was a month or two ago, or so many have gotten hired there is no one is left to blog. For all the hiring going on these boards aren't as active as they were in 2008. I think the activity on these boards tell part of the looming "shortage" story.
