Don't understand why you don't grant interviews (4,2,3)
I believe the answer is:
fail to see
'why you don't grant interviews' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'don't understand' is the wordplay.
I cannot really understand how this works, but
'understand' could be 'see' (synonyms) and 'see' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
