Question - Are you applying for other jobs also?
Answer -
This question has a very specific purpose. The interviewer wants to know that if the candidate admits that he has applied to other places or gives a canned answer. Or what the candidate think about their company.
You should never claim that you did not apply to other company. Despite this, you can say that -
