Maybe you've never had trouble before because you've become something you never used to be. You present yourself here now as someone who isn't going to interview well and believe me, this type of thing (covert negativity and alienation) is fairly easy to extract by competent interviewers. Most people are surprised at how they present themselves when viewing themselves interviewing and reveal things about themselves they are unaware of. I used to conduct employment interviews in a past life for a market research firm and that was a known aspect even before the honing of the process that has occurred over the last couple of decades.

You may THINK you'll interview well now, but unless you're an accomplished liar, your present attitude will bely itself whether you're aware of it or not. Of course, maybe you ARE an accomplished liar and will succeed ? You have to admit, that's what will be required to fleece those trying to find out about YOU, because clearly, if you're honest, you'll come across to them just like you are here. It's just a suggestion, but you might want to start preparing for that day now and reinvent your attitude.
