"We particularly welcome..." seems to imply that applicants with these characteristics will be at an advantage, or why mention it?
It’s just a fairly generic inclusivity statement, the kind of thing most organisations will have in some form or another. If people are offering an actual advantage they just say it.
Exactly my thoughts. In many places discussion of sexual orientation in the workplace (and particularly in a job interview) is illegal and if it isn’t it shouldn’t be.
It’s illegal in this country.
