Have you ever walked out in the middle of a job interview? Or seriously considered doing so? Maybe it became obvious in the interview that you would not like working at the place. Maybe you knew that you were answering the interview questions poorly. Maybe you got bad vibes from the hiring committee.
I had an interview yesterday and thought about saying that I'm sorry, I'm not as qualified for this job as I thought I was and calling it done. I had an interview where I was asked several questions on things I lack experience in. The job description didn't mention anything about these things. I still felt embarrased and wanted to hide.
I stuck the interview out though because I didn't want to be seen as a quitter. Maybe the organization will have a more suitable job for me in the future. So it's important to have a positive attitude if I ever want to be considered for future positions.
