Why do you want this job?

Answer 1

It is (less meaningless/pays more) than the other jobs I saw advertised.

Answer 2

You need to tell the interviewer at this point in just a couple of sentences or more why you feel you are a great fit for the position and for the company. Most companies want you to want to work for them, not just anyone. By showing that level of interest, you are showing you can fit in to their corporate culture.
