What is the question the speaker tries to answer? How to______ in a job intervie

Ladies and gentlemen,
    Now let me answer your last question: How to succeed in a job interview? The most important thing is that you should arrive on time; being late is not polite. You should also get dressed properly and neatly. Good manners are equally important. Don’t be too proud, neither too shy. What’s more, you should not be nervous, because it may affect your performance. Being confident can bring you to success. Finally, be honest about yourself and never tell a lie, for honesty is the best policy. All in all, doing well in a job interview means a good chance of being employed. Wish you success in your job interview.
