It seems like an easy interview question. It's open ended. I can talk about whatever I want from birth forward. Right? Not really. Below are some tips at how to answer this type of interview questions.
What the hiring manager really wants is a quick, two- to three-minute snapshot of who you are and why you’re the best candidate for this position.
So as you answer this question, talk about what you've done to prepare yourself to be the very best candidate for the position. Use an example or two to back it up. Then ask if they would like more details. If they do, keep giving them example after example of your background and experience. Always point back to an example when you have the opportunity.
"Tell me about yourself" does not mean tell me everything. Just tell me what makes you the best.
