Numerous answers are good, just stay positive. A few good examples:
Your ability to prioritize, Your problem-solving skills, Your ability
to work under pressure, Your ability to focus on projects, Your
professional expertise, Your leadership skills, Your positive attitude are some of the answers that you can give for your strengths.
Most career books tell you to select a strength and present it as a weakness. Such as: “I work too much. I just work and work and work.” Wrong. First of all, using a strength and presenting it as a weakness is deceiving. Second, it misses the point of the question.
You should select a weakness that you have been actively working to overcome. For example: “I have had trouble in the past with planning and prioritization. However, I’m now taking steps to correct this. I just started using a pocket planner . . .” then show them your planner and how you are using it.
Talk about a true weakness and show what you are doing to overcome it.
