Describe a job-related experience that involved a lot of repetition. How did you handle this?

"As an apprentice, I was given a big box of circuits to rewire. Each one had to be done the same way, and each one had to be done separately. Meaning, I couldn't do one part of every circuit and then come back and do the next part. I had to completely finish each circuit before moving to the next one. After about half the box, I realized this was a pretty boring and repetitive job. I made sure to take frequent short breaks to keep my mind sharp and focused. I also found myself saying the steps out loud as I did them to make sure I was fully focused on each circuit. I finished the whole box, and they were all done correctly, so I'd say that particular method of handling a repetitive task worked pretty well for me."
