[UK] Not rejected, but not through to first round.

Seen quite a few people mention they've got some first rounds at BBs and others saying they've already been rejected e.g. after an assessment.

I've not been rejected but not been put through, I'm guessing this either means I'm on the "B" list or I've been quietly rejected. Any thoughts?
 

Mindful that what I should probably do is just keep the fuck away from people discussing if they've got offers etc.

Thanks
