Interview preparation tips for other job seekers - Make it short and crisp!
Do not repeat what's already on your resume. Companies ask this to know how well you can speak and represent yourself.
Start with name and your background ( your field, family, etc.). Then your interests and things you like. Then end with hobbies.
End it confidently, do not end your sentence with 'umm that's all'', be confident and end it confidently!
