The second part is that it is inevitable that someone will eventually talk a good talk but be unable to actually walk the walk. That's when it's nice that we're in a right to work state. There's no point keeping someone on if they can't do the job you've hired them to do.
Of course, all that being said, this only works because we are a small shop, and the person doing the hiring is the same person who will work with "the new guy" from day one. This makes it loads easier than having to deal with hiring for someone else's department or even company.
The crowd that reads all of the software engineering books seems to be evenly split between good engineers and wankers.
I want to see a portfolio with real code behind it. I want to read your code. If I can't do that, you've probably not convinced me you're a good programmer, no matter how much you can talk the talk.
