Many college students have different kinds of problems about finding jobs which they want. Though they have strength to do, they didn’t achieve the ideal result. That’s because they don’t make full use of their networks and contacts or they don’t know how to apply for a job. People will not get the full information about them. What you are good at? What you have to show to others? That is the point. This report uses several examples of applying jobs to analyse three different sized companies: small, medium and large. And discuss how to make the good use of our networks and contacts to find the companies which we are interested in working with in the future. Also, we should get a better understanding of what constitutes a small, medium or large company. In general, you should know how the companies work, what kind of persons with abilities they are seeking, how to show them your talent to meet their needs. In these ways, you will increase the possibilities which you can be hired from the employers in the future. Good talent and work need to be shared. Resources should be fully used.
