When job candidates are asked by an interviewer why they're applying for the position, the best way to handle it is to tailor the answer to job requirements. This means emphasizing qualifications that are a match. There's nothing wrong with keeping it simple and honest; for example, for a company looking for typists, a candidate might simply respond, "I can type 85 words per minute with zero errors, and my friends told me this was a great place to work."
The question "Why are you applying for this position?" might be asked in different ways: "Why are you interested in this job?" or "Why do you want this job?" The reply should not be too general, it must always focus on communicating interest, ability and enthusiasm, and details should be provided to support each answer.
Take, for example, a finance position that a candidate wants to fill. The candidate can mention being already well-versed in the new financial regulations, and, therefore, how the position is virtually made to order. Further, stressing how the role presents a challenge that would force the candidate to remain thoroughly engaged, commanding full attention and energy, would likely make a lasting impression on the hiring manager.
