Two bright young engineers applied for the same position at a computer company. Since they had identical qualifications, the company asked the two applicants to take a ten-question test.

At the conclusion of the test, one of the applicants was called into the manager's office.

"I have graded the test, and you both scored nine correct answers and got one answer wrong. Thank you for your interest, but we've decided to give the job to the other applicant."

"And why would you choose him if we both got nine questions correct?" asked the rejected applicant.

"We have based our decision not on the correct answers, but on the question you missed," said the Department manager.

"And just how would one incorrect answer be better than the other?" the rejected applicant inquired.

"Simple," said the Department manager, "The other gentleman answered Question #5, 'I don't know.' Your answer to Question #5 was, 'Neither do I'.'"
