neurosurgeon

I'm a little stuck... Click here to teach me more about this clue!

'one does mind job in hospital?' is the definition.
I can't judge whether this definition defines the answer.

'ungenerous or liberal' is the wordplay.
'liberal' indicates anagramming the letters.
'ungenerous'+'or'='ungenerousor'
'ungenerousor' is an anagram of 'NEUROSURGEON'.

'perhaps' is the link.

Can you help me to learn more?

(Other definitions for neurosurgeon that I've seen before include "doctor" , "top person in theatre" , "One operating on brain, spinal cord, etc" .)

I've seen this clue in The Guardian.
