Jason Frank, the marketing and research director at the communications agency SAS, says this creates tough competition for the good graduates. "Companies are finding it difficult and expensive to attract top talent," he says. "The people doing this sort of thing (running their own businesses) are often the sort of people that they want." The supermarket giant Sainsbury's conducted a lot of research into what graduates wanted in an employer and used this information to develop appealing graduate advertising. Unfortunately, the reality didn't always match the glitz. "People would say things such as, 'Where's my office？' but there wasn't one--it's working on the shop floor," says the director of the recruitment department. This mismatch was one of the reasons cited when people left the scheme early. "Where it becomes difficult for us is that retail isn't seen as a sexy career. In the past we've fallen into the trap of trying to compete about being sexy, but now we're looking at what the job actually involves. Let's be really honest with them about what life's going to look like." Now graduates know before they start that they will be expected to work hard on the shop floor in return for early responsibility, such as running their own team. Frank says that a warts-and-all approach to recruitment marketing will probably reduce the number of applicants, but should also make sure the people who do apply are a better fit for the company. "When people go in with the wrong expectations everyone's wasting their time. The student starts on a bad note, there's not a cultural fit, he might not have the right skills and the company will spend ￡100,000 training him and he will be gone in two years," Frank advises companies to use a niche marketing approach that targets segments of the student population, rather than trying to get everyone on every campus to read their brochure. It's also up to students to ensure that they think carefully about what work environment will suit them. Frank says that many fail to do any research at all. "They end up sending out applications to the companies that they have heard of in campus advertising, regardless of whether they truly know what the company does." By his words in Paragraph 2, Jason Frank means that the drop in the number of graduates who enter the job market ______. A．makes it difficult for good graduates to start their own business B．creates fierce competition among companies to attract good graduates C．creates tough competition among graduates to get a position in large companies D．makes it difficult for companies to recruit talented people with work experience
