The right details
Another trick to answering STAR questions effectively is to avoid generalities. Consider the difference in these two answers:
Before: “I had a rough project. I spoke with the person who wasn’t doing their work and it got better.”
Better: “I had a team project in my marketing class where one person wasn’t completing their tasks and was holding everyone up. I approached my classmate privately and asked if he needed help. He admitted that he didn’t understand the project and wasn’t sure where to start. I offered to show my teammate an easy way to complete his research and gave him a few simple resources that could bring him up to speed. After our conversation, my classmate made a complete shift. He finished all his work, before the deadline, and we got an A on our project.”
Notice in the above examples that the interviewee gave just the right amount of detail to make the story clear, without rambling. And consider how many skills this candidate just succinctly demonstrated – team player, problem solver, strong communicator, among others.
