Yep! that has happened to me. I was encouraged to go for it by my boss. In fact I would not have gone for it if he did not suggest that I apply. I didnt even get an interview.

Try and be brave and ask why you didnt get an interview. I did. I think it made my boss respect me more how I handled the situation (secretly I was just thinking, dont expect me to do half of the extra things I normally do seeming they mean f all to him LOL).
