When I am describing myself to the interviewer, should I say I am post graduate or Post graduated. Which one is the perfect ?
You can say :
I am a post graduate
I have a post graduation degree in (subject)
I have done my post graduation in (subject)
In my opinion it is better to say the second one, i.e,I have a post graduation degree in (subject), as it also gives you a chance to mention which subject you took in your post graduation.
