What is true about the Google online questionnaire

单项选择题

Pressed by competition and its own success, the popular search engine Google has created an automated way to search for new employees who are fully appropriate as well as high-achieving. In a project, the 100, 000 people who fill in online job applications for Google each month will be asked to complete a complicated questionnaire(问卷)exploring their attitudes, behaviour, personality and backgrounds going back to their school days. The questions range from whether applicants have ever set a world record, to whether their workspace is messy or tidy or what magazines they read. Answers are studied by Google"s mathematicians to calculate a score meant to predict how well a person will fit into the organization"s diversified and competitive culture. Psychometric tests(心理测试)are already used by more traditional companies to select workers, but they are unheard of in a company like Google, which is built on a belief in individual talent. The online questionnaire is based on the answers to 300 questions sent out last summer to every employee at the head office in California"s Silicon Valley. Some questions were factual: What programming languages are you familiar with What Internet mailing lists are you on Other questions, however, tried to establish personality and behavioural characteristics: have you ever tutored another person "We wanted to cast a very wide net, " said Laszlo Bock, Google"s Vice-President for People Operations.
