I found this blog article from Dana Manciagli on LinkedIn as one of today’;s featured posts. This is a great checklist of reasons why you may not have gotten an interview callback. All of these reasons have to do with what you say, how you say it and why you are saying it. Our mouths can get us into a lot of trouble, including tanking some otherwise good interviews. I have seen these in action (and committed some of these blunders myself).
