My weakness is that I'm an introvert, It isn't that I'm shy from others, or that I cannot socialize, it's that I would rather do my work independently than have to worry about the people around me.
My weakness is that I'm slow. I like to take my time to do my job thoroughly than rush and make mistakes.
These are a few ideas of myself in case in a future interview someone asks me what my "weaknesses" are.
I read this one before " I'm a perfectionist, I would rather take my time and do the job perfectly once than have to rush through it and repeat it several times." I'd be lying if I said i'm a perfectionist though.
