When companies need new employees, they usually place advertisements in newspapers in order to attract as many applicants as possible. But many large well-known companies hire new people frequently without putting advertisements in newspaper, because they already have many resumes on hand. Therefore, it is not always a best way to apply only to companies that place ads in newspapers. A person looking for a job is advised to send his resume with a cover letter to a well-known company even if a position is not then open. He can follow up with a telephone call to inquire if his resume has been received and if some jobs are available. If there is not a job available in the company at that time, he can ask that they keep his material on file and contact him in the future when something is available. If later he sees an advertisement in the newspaper for a job with that company, he may call the company whether they will consider him for the position. So, a person has nothing to lose and everything to gain by sending in his resume. Which of the following is NOT true
A．Many companies prefer to hire new employees by advertisements. B．You should send your resume and cover letter when you look for a job. C．You are advised not to send your resume to a company if no jobs are available. D．You can telephone the company and find out whether they have got your resume.
