The two most dreaded questions in a job interview usually come back-to-back. "What are your strengths?" and "What are your weaknesses?" are difficult to answer. For strengths, pick a skill you have that applies directly the job and use it as your answer. For instance, if you're applying as a file clerk at a hospital, mention that you're very good with details and can keep track of a lot of things at once. Tailor your strength directly to the job description you applied for in the first place.
