     It is well-known that many people look for a new job through newspaper advertisements and the

Internet, which are great ways. However, job fairs (招聘会) may open up more doors for you and allow

you to build a sound future career(事业).

     A job fair allows many companies from your area, as well as other areas to gather together to recruit

suitable people to help the development of their business. These companies typically attend the job fairs

to accept new people into their team.

     Take Cumberland in Maryland as an example, the job fair is held at the Holiday Inn's large

meetingroom, which is next to the main hall. Dates change but the event lasts from 8 am until 6 pm throughout the whole week. The job fair is usually held several times every year; dates can be found in the

Cumberland Times News or on the newspaper's website. Also, information about the companies that will be attending, is offered, along with these companies' web addresses for you, so that you can make more

preparations based on the needs of the companies you are interested in.

     You must know that you can't show all of your talents, skills and abilities on a resume (简历) alone, so

it's important to leave a good and lasting impression in employers' minds in a very short time. So you must make sure that you have given your best to the employers. Get a handshake with all of the employers you

speak to and, introduce yourself clearly enough so that they will remember you in case you get an interview in the near future. Seldom, people are employed on these job fairs for the qualifications (资格证书) they

show.

     You should take with you at least 20 copies of your resume. Prepare a notebook and a pen to write

down what is told you by the employers. This shows your interest and willingness to learn.
