Answer:
A good response to "What is your biggest weakness?" is letter D) "I'd like to work on getting myself better organized. I have been trying out a new system."
Step-by-step explanation:
When at a job interview, it is very common for applicants to be asked what their weaknesses are. The interviewer expects a suitable answer. If you answer with option A, claiming you are a perfectionist, you will be answering with a quality that can be both a strength and a weakness. The interviewer will see that you are trying to deflect from the question, and the result will probably be negative for you. If you answer with option B, claiming you don't have any weaknesses, the interviewer will think of you as a liar. Everyone has weaknesses and, if you can't think of any, that means you are most likely an arrogant person who is not open to improvement. Option C may even be the truth for you, but it is bad for the employer. If the employee takes frequent breaks, he will cost the company precious time and money. If you have trouble staying focused and is not allowed to take many breaks, you'll probably make many mistakes.
Therefore, the best option seems to be option D. When you admit a flaw that is a not terribly bad and claim to be working to get better, you show the interviewer you are humble, honest, and capable of improving.
