Thanks to everybody for such kind words and encouragement. And, I hope those of you still in the process have success.
I'm pleased to say that I was one of four that was called back yesterday to come in for a second interview. However, I had a few days to think through the details, the job and what I want. I followed my instincts and declined because I feel that this wasn't the right job for me.
I'll continue to keep my eyes open and apply for anything that seems interesting. I'm thrilled that I was able secure an interview and that an employer was seriously considering me. It's given me great confidence knowing that I have options.
Good luck to everybody else!
