Advice
This is a difficult question and almost preloaded to allow the interviewer to question you further. If you are going to say that you are successful you need to be able to provide evidence as to your success, regardless of the level you are at in your career. If you are just starting your career you will need to be able to show that you are academically successful or successful in your sporting life. If you have enjoyed a long career you need to be able to point at the moments in that career when it could be said that you have been successful. Do not make the mistake of saying yes but being unable to back this up with evidence of your success.
Examples of success can be anything from achieving a particular qualification with a good mark, constantly achieving promotion throughout your career, joining a firm and increasing both your income and the firm’s income through new measures, receiving an award or providing general examples of an ongoing nature of things you have done that have been successful.

In every job I have had to date, my employers have provided me with an excellent reference and indicated they would be happy to employ me again if the opportunity arose. I would like to think that I have been successful throughout my career to date”.
Or:
“Yes. You can see from my CV that I have enjoyed a successful academic career to date with good A Levels, consistent marks throughout my schooling and culminating with a strong 2:1 degree from a good university. I hope to be able to start my career and continue it with the same level of success”.
