The interviewer knows that obstacles may arise sometimes. Describe an unpleasant experience or a time something didn't go as planned and how you handled the situation.

"In my previous position, I was assigned a new coworker for the night shift. He was not very helpful because he kept falling asleep on the job. However, there was a job to be done whether or not I had any help. I am very productive when I work so I was able to complete the work of two people individually within a reasonable amount of time."
