If i selected for job, how can i help our company

That depends.

What sort of job is it?

What would you be doing?

Do you have the education or knowledge to do this job?

Have you done this type of work before?

We need a lot more information.

If you do not do research on the company or you do not know the job you are applying for, then you will not be able to answer the question and you will have no shot at getting the job.

Find out more about the company. We need more info to answer question better. What country? What type of town? How old are you? Other details, please.

This is in the wrong thread and needs to be moved to the interview questions thread within Business & Careers!!
