Back in the 80s I had one interview where the recruiter seemed obsessed with my accent (or lack of one). I was born and raised in the North, but went to uni in the south and didn't have a distinct northern accent:
Recruiter: So you were born and grew up in [Northern City]
Me: Yes, and then I went to uni in [southern town]
R: But you haven't got a northern accent?
Me: Er, well, not a strong one, no . . .
R: So why is that? Have you deliberately tried to lose it?
Me: Not really, I guess I just don't have one.
R: But everyone from [Northern Town] has a XX accent, so why don't you?
Me: Well, I'm not sure that's true, it's just stronger in some people
R: What sort of school did you go to? Did they give you speech and elocution lessons?
Me: An inner city comprehensive, and no, I didn't have any speech lessons
R: So how do you explain your lack of a regional accent?
Me: Er, perhaps because my parents listened to Radio 4 sometimes?
It wasn't as if it was relevant to the job - it wasn't for a radio or TV host or a call centre or anything!
