Dear Nekoshema:
Dealing with such is a one step at a time thing, you take one step, feel the anxiety, calm yourself, move slowly toward the goal, relax, take another step and so forth. There is no One time solution that will work “from now on.” It is not going to be a smooth ride. Prepare for the interview, type questions you may be asked and practice the answers. Be as authentic as you can but self- respecting in your answers. You can express your less than … perfect confidence but in a way that is self dignified. You can say you don’t know if you have the required skills (if you don’t) but that you are very motivated to learn. So preparing for the interview is one step, setting the interview is another step, dressing for it is another step. going there, etc. One step at a time.
