Stupid question that I should really know the answer to and I think I'm overthinking this...
Can I submit a 'personal statement' when the job listing asked for a 'cover letter'? Surely they don't care about the address header and 'yours sincerely' stuff, it's the content that matters (that would be the same in either case). If the letter format is essential, then who do I address it to? HR person? Head of dept (although that's not entirely relevant for this post, which is across departments)? The person who's listed on the job advert as the person to whom to address informal enquiries (even though they seem to have no connection whatsoever to the actual departments the job is in)?
In case it matters, they simply ask for a CV and covering letter. No application form, etc.
