“This is a great example of what is known as a negative question. Negative questions are a favorite among interviewers because they’re effective for uncovering problems or weaknesses.
The key to answering negative questions is to give them a positive spin. For this particular question, your best bet is to admit to a weakness that isn’t catastrophic, inconsistent, or currently disruptive to your chosen professional field, and to emphasize how you’ve overcome or minimized the problem. Whatever you do, don’t answer this question with a copout like ” I can’t think of any,” or even worse, “I don’t really have any major weaknesses.” This kind of response is likely to eliminate you from contention.”
This is a possible answer:
“I admit to being a bit of a perfectionist. I take a great deal of pride in my work and am committed to producing the highest-quality work I can. Sometimes if I am not careful, though, I can go a bit overboard. I’ve learned that it’s not always possible or even practical to try and perfect your work; sometimes you have to decide what’s important and ignore the rest in order to be productive. It’s a question of trade-offs. I also pay a lot of attention to pacing my work, so I don’t get too caught up in perfecting every last detail”
