You leave a job interview feeling pretty good about yourself and your chances for landing the job.
Then you have the rest of the day to think about all the things you could have done better during the interview.
Later, you are totally conviced that you bombed and you'll never get a new job.
That was my day today. Interview at 9:00 AM, by noon I was second guessing myself, and now...
I am still keeping my fingers crossed.
