While this question is an invitation to do some chest pounding, remember to illustrate strengths that will benefit the employer and are relative to the position. For example:

☛ being a problem solver

☛ being a motivator

☛ being a natural leader

☛ the ability to perform under pressure

☛ a positive attitude

☛ loyalty

Are typically all solid strengths, but again, consider the position. For example, mentioning you are an excellent “team player” in a job where you largely work alone suddenly becomes irrelevant to the employer and demonstrates a genuine lack of self awareness.
