The main reason of asking this question(tell me abt yourself) is not for looking for any
specific answer, or a answer in any format, this question is mainly
asked to:

1. Gauge the aptitude of the person
2. How easily a person understands the contxt of the question (I have
interviewed people, who talk about their birthplace, date, parents
etc. A technical person is not looking for such statements. This is a
apt senario .. that this answer is when HR is asking not a technical
person)
3. To get the interview started
