How you view a victory can be a substantial determining factor on whether or not you will be a good fit for this particular role. Share with the interviewer your thoughts on success, and what a successful day would look like to you.
"I define a day as successful when I have spent some time working on a project that I am passionate about, I have helped someone else succeed, and I have learned something new. These three factors would equal a very successful day for me."
"I would consider my day successful if I were to complete my tasks on time and deliver more than my employer expected of me. If I were to receive a pat on the back or a verbal accolade, even better."
"To me, a successful day is one where I was able to learn a new task and apply it to help someone out. I enjoy days where my project deadlines are on time, with little resistance, and where my client recognize the hard work that I put forth for them."
