Official negotiations haven't even begun, and won't before the UK pulls the trigger (triggering article 50).
It seems as if informal negotiations did not lead to anything; many politicians across EU member states and from the EU institutions indicated from conversations they had with either May, Johnson or Davis that so far the UK haven't been able to come up with anything other than
"have the cake and eat it". Unsurprisingly, this is rejected.
Edit: This article gives a sense of how it's going. There was a more recent one I had in mind but can't retrieve.
