First of all, give a profile of your professional background and experience. this should composite about 70% of your answer. Use this opportunity to tell the panel your relevant professional information that makes you a better fit for this role. Secondly, dive into a little of your personal life(20%). This should be reasonably brief. Prospective employers are most interested in your skills than your personal life. Finally, tell the pannel an interesting thing about yourself you wish the panel to know. This could be your hobby, sports club you support. This will trigger an interactive interview. It also calms your nerves down ahead of technical questions. I hope this helps.
