Q: What is your biggest weakness? A: Coca Cola. It's empty calories and bad for your teeth, but I just love drinking Coke. Oh, you mean work related? Sorry.....
I would say truthfully, "My biggest weakness is an inability to suffer fools but I've been working hard and am now much better at it."
I've interviewed many "would be" traders for our firm. I've asked this question many times. What I'm looking for is how objective is this "would be" trader? If I get the pc weakness into strength answer like "I work too hard and often work well into the night", then I know it's bs and this "would be" trader is going to lie to me when I ask him/her to defend a position there're holding that's underwater. What I want is the truth. If you're a procrastinator...say so. I'll ask you how you work with it and you can say "I make lists of all work I need to do and work from the list" to look good. If you freeze when the market moves 3+% against your position....say so. All else means..."I don't know if I can trust you with my firms money".
"My biggest weakness is also one of my strenghts" - "the fact that I am still young and don't have a lot of Life experience yet, but being young and wanting to learn could offset that". FWIW Don
I used to say my biggest weakness was operating a computer but I had overcome that by reading books and magazines, that really seem to impressed them and it also showed that you are a real learner.
I say "I do not have any weaknesses because every time I find a weakness I work on it until it becomes a strength. All I have are strengths."
