Why be secretive about abusing a loophole with a company you might have a relationship with?
Honestly, if I saw white text on a CV then I’d likely skip the candidate because I wouldn’t trust them and trust is everything. But if I saw someone being open and explicit on their CV, then I’d at least trust their honesty a little more even if I didn’t agree with the technique.
What irony, the company that uses an impersonal approach to hiring is somehow in the right here.
If I were reviewing applicants, I might see that as a point in the applicant's favor. It's not only being aboveboard, it also shows a creative solution to a technical problem.
I've seen this on someone's resume and loved it. They also had a good resume in general, which helps.
