So I assume you were speaking to firms more than 3 years ago on immigration matters? Because that's how long we have been waiting for an update on them, and considering firms recruit 3-4 years inadvance, they are rightfully placed to say "we don't know" when it comes to visa processes throughout that period. Joys of Brexit and a incompetent government.
I am not "waving" away anything - you seem to only read to what you want to into what I post. I definitely didnt say "there definitely isn't discrimination because law firms work hard". You are quick to deem graduate recruiters incompetent and all I am saying is that I think that is unfair - I clearly have personal reasons for thinking that. I find it pretty insulting to both me and a lot of the people I know.
Look up some of the cases on "recent graduate" rulings and you might find some rationale on why employers can do this.
I will bet money on it that CC had a conversation with employment lawyers to say "we are publically going to go out and say this is our policy on recruitment, do you think there is a risk of discrimination" and lawyers, rather than HR will have told them that risk was either minimal or non-existant based on current case law.
It will be interesting to see if anyone does want to test that theory out further by making a claim against them.
