Question - Don't you think that you are overqualified for this position?
Answer -
This is trick of the interviewer to trap you and judge how boasting you are?
So, be alert to answer this question and don't even hint to the interviewer that you are overqualified although you are.
This is a good answer:
"I think I am qualified for this post because I am just a beginner and have lots more to learn. I think qualification is not only a matter of theoretical knowledge or results; it also depends on practical knowledge and learning. When I get practical knowledge, I will consider myself just a well-qualified not overqualified. Because learning never ends."
