@Lidiya - if you said that, I would ask why you think that's a negative ;-)
From the original Dilbert 1995 comic strip:
Interviewer: "Your resume is impressive. I only have one question. What do you consider your biggest fault?"
Dilbert: "Sometimes I work too hard."
Interviewer: "Why is that a fault?"
Dilbert: "Well . . . Uh . . . I work so hard that I forget to eat and bathe for days. Eventually I starve to death at my desk. I become a bloated, stinking corpse. Insects breed in my body. I spread disease to the entire company."
Not a good story ... :-D
"What is your biggest weakness?"
"My biggest weakness is I think most interview questions are psycho-babble bullsh-t, and the interview process a complete waste of time"
Yeah, I didnt get the job. Eventually I had to become self employed.
You can describe a weakness that is also a strength. You might say, "I sometimes find it difficult to delegate work to other people, because I prefer to complete it myself so I know it has been done properly."
