I have two interviews today and tomorrow and I already feel I am not going to do well.

Being demoted in my job has effected my confidence greatly, and I still have no answers from HR as to why or what happened... if it was due to my performance or strategies.

I know I am going to fail these interviews and. not get a job offer. I might as well just throw in the towel now and accept that I am a big fat failure in my career.
