Almost every employer will violate their employee's rights without a second thought in ways they consider "unimportant but necessary to the business" ... as long as that continues it should be a 2-way street.
The point is not necessarily whether it's morally wrong to violate a contractual agreement when the other party is likely to do so.
It's that the interview process proposed by the G[...]P may force the candidate to do things that may be illegal to pass the interview. The candidate is of course responsible for their own choices, but the point is that as an interviewer, if you force your candidates to do this, you might short list those who have a tendency to violate contract terms.
This might work out for some, but I'd say it's a fair point to bring up.
I'm an employer right now in my small company. Don't see any reason to screw up my employees, on the contrary, I see it's much better to work in a friendly environment. There's no such "unimportant but necessary to the business" things.
