Wrong- you use 'I' when it's the subject of the sentence and 'me' when it's the object of the sentence. Here 'interview' is the subject and Kev and Sal are the object of the sentence. To check the correct word simply leave out the other person and see how it reads. Would you say '' an interview with me'' or '' an interview with I'' ? If you accept that the correct wording is '' an interview with me'' then the correct heading here should be '' an interview with Kev and me.''
B.
This to me confirms nothing other than the fact that English is one of the most inconsistant languages in the world, and yet due to weight of power and politics it has been chosen to be
the international language.
I say this because my understanding - which is of an English GCSE standard - is that you could say:
Kev and I in an interview.
But due to some strange mechanics you can not say:
An interview with Kev and I.
One thing that I do find funny is that how people with english qualifications believe they "know" the language better and yet the producers of the English dictionary are forever stating that our language changes on a yearly basis - that includes grammer. There are ofcourse those that would argue for the worse, but then I am quite happy we don't all march around talking like we had walked out of a Shakespear play . . . . .
The basic essential of any language is that the intended message is being communicated, cave paintings, art, sign language, sculptures, tappestries, fashion, music - these are all languages and to that extent I find it hard to see that any language is an exact science.
