Please tell me about yourself?

I am an engineer but want to make successsfull business only

There is no right answer because every single person on the planet is individual. However, you need to put yourself in the shoes of the interview panel and think what they might like to hear, They will want to know that you are confident, well rounded, have many interests but that these do not get in the way of your ability to work hard, They want to see that you are passionate about something and have the capability to see things through. So, telling them about hobbies and projects you participate in is a good idea, but don't go on at great length and be boring though!
