I think either the RED recruiter for BHD is lagging or there is a massive communication gap between the recruitment team.
It just doesnt make sense to keep BHD invites higher on GGn, which in itself is tougher to join than RED.
If you meet the requirement do go and get these invites, I am starting to think even they might close recruitment soon, BHD is a nice place with the same exception of their staff.
