This is one of the most challenging behavioral questions you can be asked during a job interview.
The best way to describe your greatest accomplishment while only including relevant information is to use the STAR technique:
- S= Situation. In what context did your greatest accomplishment occur?
- T = Task. What challenges did you face or what goal did you want to achieve?
- A = Action. What action did you take? What skills did you use?
- R = Result. What was the result? What did you learn from the experience? Why is this your greatest accomplishment?
Ideally, you should talk about a workplace accomplishment.
Make sure your answer is relevant to today’s job market and the skills required of today’s candidates.
