Tell me about a time when you had to assist a coworker.
How to Answer
The best way to answer this question is by telling the interviewer a story. You should start with explaining the overall situation: tell them about the project/task, what your coworker's responsibilities were, what they were having trouble with/needed assistance with, how you helped them (specifically) and the result/outcome of your collaborative work. It is important to show the interviewer that your assistance contributed to the success and/or completion of the task/project.
