Rubbed in when auditioned (7)
I believe the answer is:
applied
This could be a double definition.
'rubbed' is the first definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'when auditioned' is the second definition.
Although both the answer and definition are past participle verbs, I don't see how they can define each other.
'in' is the link.
Can you help me to learn more?
(Other definitions for applied that I've seen before include "Type of science" , "Turned" , "Put into service, made work" , "Went for university place" , "sort of maths" .)
