I believe people should think about what they say. I also don't buy the "identically qualified" candidate argument. IMO HR departments and others tend to focus more on personality than skills. I have worked for many companys where everyone got along, yet a few of us pulled the majority of the weight because nobody else had a clue what they were doing.

I have also worked for companies where we where most or all of us were skilled at what we did. As you would expect with a group of intelligent people, we didn't agree on everything. We were also the most productive group of people I have ever had the pleasure to be a part of!

I will take knowledge and capability over personality any time. If you pull your weight, and if you try to do things correctly, we will get along just fine.
