This is a common question asked for fresher’s. It is recommended that you say “no” and give a justifiable reason.
You can say like: No, I don’t have any plans for higher studies. I am looking to start my career with a good organization like yours.
Or
You can say like: I want to look for higher studies after some years for my career improvement, but not as of now.
If the company needs it, I will do for further studies.
Or
I am interested to do IT certifications instead of further studies.
