Be careful answering this question. You don't want to imply that you are criticized consistently on the job, but you also don't want to imply that you're perfect.

It makes sense to mention things that are not specifically related to the job for which you're applying. You want to emphasize that the criticism or weakness does not affect your ability to perform the job well.

You might also choose to mention a "weakness" that might actually be considered a strength on the job. For example, you might say that some people have said you are very critical of your work, but you can explain that you have a keen attention to detail, and you bring that detail-oriented nature to the workplace.
